==Introduction==

This page is mainly concerned with troubleshooting '''Akonadi''', as there are inevitable glitches in early stages of migration.  For many people the first signs of '''Akonadi''' activity will be in '''KDE SC 4.4''', and many will be confused by it.  For a brief description of the purpose of '''Akonadi''', see [[Glossary#Akonadi|this Glossary entry]].  You will also find useful links to further reading.  Once the inevitable teething troubles are over, '''Akonadi''' will provide a power-house usable by many applications.

===Understanding the Structure===

You can, of course, simply use '''Kontact''' to manage all your addressbooks, but if you have a backup system in place, for instance, you'll want to know where your data is, and how it's handled.  The page [[Akonadi_and_AddressBook|Akonadi and AddressBook]] will help.

== Troubleshooting Tips ==

* When reporting problems with the '''Akonadi''' server, always include the comprehensive self-test report. This report can be obtained from the self-test dialog which shows up whenever the '''Akonadi''' server was unable to start successfully. You can find the selftest dialog in the kcmmodule that is accessable via:
{{input|1=kcmshell4 kcm_akonadi}}
* Starting the '''Akonadi''' server manually on the command line can result in additional useful information. This can be done by running the following command on a console:
{{input|1=akonadictl start}}
Similarly, with this command the Akonadi server can be stopped again:
{{input|1=akonadictl stop}}
This command gives more useful information:
{{input|1=akonadictl status}}
==Common Problems==

===Kontact doesn't start - and doesn't tell me anything===

If '''Kontact''' doesn't start, and you see no error messages, check that '''Akonadi''' is running.  '''Akonadi''' should start on demand.  If yours doesn't, you will have to start it before '''Kontact''' will start up if you have any migrated resources (most likely '''KAddressBook''').  Use the ''Akonadi Tray icon'' (get this by typing "akonadi" into '''KRunner''') or type the commands into '''konsole''' to start it.

===Kontact doesn't start - version II===

'''Kontact''' has been known to be hit after an update.  If this happens, try starting '''KMail''', '''KOrganizer''' or any of the other applications from '''KRunner''' (or '''Konsole''').  Chances are high that they will work as stand-alone apps while you find what went wrong.  This mainly affects version 4.4.0.

===Folder not found: "/Local"===

Some people have reported this error, when '''Kontact''' would not start.  In some early versions of 4.4 there seems to be a bug in the migration that is telling '''KMail''' to look for local mail in ~/.local/share/Local, a directory that had not been set up.  The solution for this is not to attempt to correct it, but, with '''KMail'''/'''Kontact''' closed, to open the '''Akonadi Console''':
* Use '''krunner''', Alt-F2, or
* "akonadiconsole" '''konsole'''

Then remove the resource that it says is for local mail.  You should now find that you can start '''Kontact''' or '''KMail''', and that a new resource will be created, pointing to ~/.local/share/local-mail

===There are other new folders under ~/.local/share/===

Yes.  If your addressbook has migrated correctly a new resource will have been created as ~/.local/share/contacts/

===What are /usr/bin/akonadi_maildir_resource and /usr/bin/akonadi_maildispatcher_agent?===


The ''akonadi_maildir_resource'' is created automatically by the ''akonadi_maildispatcher_agent'', while the latter is always started together with the ''Akonadi server'' as it provides basic functionality (e.g. sending mail) that is used by all mail applications that are (and will be) based on '''Akonadi'''. So it is ok that these two are running, as a user you can simply ignore them.
This autogenerated akonadi_maildir_resource will always point to ~/.local/share/local-mail/ which is your "Local folders" account where your local folders and emails will be stored.

At this point, in '''KDE SC 4.4''', mail is not yet being migrated.

===Nepomuk Indexing Agents have been Disabled===

'''Kontact''' is now working, but you keep seeing this notice:

[[image:NepomukError.png|418px|center]]

The most common reason for this notice is that '''Nepomuk''' is simply disabled in '''System Settings'''. Please try enabling it in '''System Settings''' under <menuchoice>Advanced -> Desktop Search -> Basic Settings</menuchoice> by checking "Nepomuk Semantik Desktop" and clicking "Apply".

If this does not help (or if the option was already checked when you got the error) and if you have previously been using prereleases of '''KDE SC 4.4''', you may be affected by a change to the database layout (due to an upgrade of the '''Virtuoso''' database server from version 5 to version 6; production releases of '''KDE SC 4.4''' are expected to be shipped with '''Virtuoso''' version 6). The following commands should get it working again:

{{input|1=qdbus org.kde.NepomukServer /nepomukserver org.kde.NepomukServer.quit
rm -r ~/.kde/share/apps/nepomuk
rm -r ~/.kde4/share/apps/nepomuk
nepomukserver}}

Note that the above commands will '''not''' enable '''Nepomuk''' permanently if it isn't already enabled, you have to use '''System Settings''' for that.

A running '''Nepomuk''' is necessary to have a working '''Akonadi''', and thus a working '''Kontact'''.  However, you can disable the '''Strigi''' file indexer, which is not needed for '''Kontact'''. '''Strigi''' file indexing is used for desktop searching only, which is unrelated to '''Kontact'''. Just make sure '''Nepomuk''' itself is running correctly for '''Kontact'''.

In '''Kontact''', '''Nepomuk''' is used for many different things, ranging from displaying upcoming birthdays, over handling free/busy lists to showing a contact photo in the message viewer. If '''Nepomuk''' is not running, several different things in '''Kontact''' will cease to work. The notice is there to warn you about the reduced functionality. Enabling '''Nepomuk''' as described above fixes the problem.

You can check if '''Nepomuk''' is correctly running by typing:
{{input|1=akonadictl status}}
===I want to use my current Address Book and Organizer - Can I?===

Yes.  When you use the ''Akonadi Console'' to add a resource it allows you to choose as ''Standard Addressbook'' - point that to your std.vcf should work fine.  Migration does not destroy your old addressbook.  You can continue to use it, though you will lose any benefits that '''Akonadi''' can bring.  Alternatively you can have both an '''Akonadi''' addressbook and your original one, for a time, if you feel safer that way.

===I can't see any details in my Address Book===

At the moment, the cause of this is not identified, but the cure is simple.  Close '''Kontact''', and start '''KAddressBook''' as a stand-alone application.  After you close it you will be able to use it within '''Kontact'''.  It seems that something is not being triggered when '''Kontact''' launches, and I expect this to be identified and fixed soon.  This seems to mainly affect version 4.4.0.

===My contacts don't show when I use the Select button in KMail===

Check <menuchoice>System Settings -> Advanced tab -> KDE Resources</menuchoice>.  Make sure that your '''Akonadi''' controlled address book(s) are listed there - add them if necessary.  At the same time, it's a good idea to make your main '''Akonadi''' addressbook, usually called "Personal Contacts", is set to be the default.  More details of how this can be found in [[Special:myLanguage/KAddressBook_4.4#Setting_up_your_New_AddressBook|here]].

===How do I get my Groupware addressbook back?===

Two solutions: using the old framework or the new one.

Old framework: In ''akonadiconsole'', add a "KDE Address Book (traditional)".  The KDE Address Book means you can set up old kresources for '''Akonadi'''.  In the configuration of "KDE Address Book (traditional)", you point it to an "IMAP over KMail" ''KResource'' and in '''KMail''', the groupware options should be enabled.  This should work for '''Kolab''', '''eGroupware''' and similar addressbooks - you will need to check the options to make sure that the correct type is selected.

New framework (only tested with '''Kolab'''): In the '''Akonadi''' configuration module add an "IMAP E-Mail Server" resource, and set up your mail server name, username and password, then click '''Auto-Detect'''. Run this command to see it:
{{input|1=kcmshell4 kcm_akonadi}}
Then add a '''Kolab''' resource. The next step is to wait for the imap resource to synchronize, which can take quite a long time. The status will appear in the '''Akonadi''' configuration module. If nothing happens, try restarting '''akonadiserver'''. After some time the '''Kolab''' addressbook(s) should appear in '''KAddressBook'''.
<span id="You experience long delays when sending mail"></span>
===You experience long delays when sending mail===

This is accompanied by '''KMail''' freezing until the mail is actually dispatched.

A bug has been found in the way '''Nepomuk''' checks addresses, which can cause huge delays.  This is fixed for SC 4.4.1.  If you cannot get 4.4.1 yet, there is this work-around:

Close '''Kontact''', or '''KMail''' and '''KAddressbook''' if you are running 
stand-alone apps.  Disable '''Strigi''' in '''SystemSettings'''.  Stop '''Nepomuk''', delete the database and restart '''nepomukserver'''.  The actual commands you need are (as user):

<!--T:42-->
{{input|1=qdbus org.kde.NepomukServer /nepomukserver org.kde.NepomukServer.quit
rm -r ~/.kde/share/apps/nepomuk
rm -r ~/.kde4/share/apps/nepomuk
nepomukserver}}

This will, of course, wipe out all the database, including any tags you've 
added.  In theory, I understand that it's possible to do a more selective wipe 
of the database.  If this matters to you you can find the instructions at
[http://techbase.kde.org/Development/Tutorials/Metadata/Nepomuk/TipsAndTricks#Remove_all_Strigi-indexed_data this page]

===IMAP Resource always claims to be offline===

Even though the system has an internet connection, the IMAP resource refuses
to switch to online state.

This bug is caused by a misconfigured NetworkManager installation on your system. Check the output of
{{input|1=qdbus --system org.freedesktop.NetworkManager /org/freedesktop/NetworkManager org.freedesktop.NetworkManager.state}}
If it is '4' (Disconnected) but you can access the Internet, then your NetworkManager is indeed configured wrong. If it is '3' (Connected) the problem
must be somewhere else. Under Debian this behavior can be caused by interfaces defined in /etc/network/interfaces, which are not controlled by NetworkManager.
To fix this, simply remove the entries from /etc/network/interfaces and let NetworkManager handle them.

{{Note|The following update was entered without any formatting and appeared difficult to understand. I have added formatting to try to remedy this. Please correct this if I have misunderstood anything}}

Update (11/'12), Kubuntu 12.04 LTS (Precise Pangolin):

The states have changed to '20' (disconnected), '40' (connecting), '70' (connected):

{{Input|1=qdbus --system org.freedesktop.NetworkManager /org/freedesktop/NetworkManager org.freedesktop.NetworkManager.state}}

should return, if connected:
{{Output|1=70}}

WLAN switched off; results in:
{{Output|1=20	# new State for 'not connected' (formerly '4')}}

WLAN retrieves address:

{{Output|1=40}}

=== Can't read  any details of some messages or big delays to read it ===

if you aren't able to read some emails and see a message with " please wait ... ", you may logout and login KDE session to reinitialize all processes, might help. 

== Some Technical Issues ==

=== Nepomuk ===

Starting with KDE 4.4, it is required that '''Nepomuk''' is running in order for '''Akonadi''' to work correctly. '''Akonadi''' will check this and display an error dialog on startup if this is not the case.

'''Nepomuk''' only works with the '''Virtuoso''' backend.
You can check whether the '''Nepomuk''' is running with the correct backend by using the '''Akonadi''' self-test dialog, as described above.

Although '''Nepomuk''' is required to be running, you can still disable '''Strigi''' file indexing, which is usually the most resource-intensive part of the '''Nepomuk''' framework.

=== Apparmor ===

Some distributions using '''Apparmor''' have it set up in a way that prevents '''Akonadi''' from running its internal database server. This can result in a variety of fuzzy error messages, including but not limited to the following:
{{output|1=unknown error 255 when running akonadictl
"DB error: 'Could not open required defaults file: /home/$username/.local/share/akonadi/mysql.conf"}}

You can solve this by running the following command with root privileges then reload apparmor:
{{input|1=aa-complain mysqld}}

On ''Kubuntu'' this is:
 
{{input|1=sudo aa-complain mysqld
sudo /etc/init.d/apparmor reload}}

Note that you might be using '''Apparmor''' even if it does not show up in the process list.

Also note that some distributions ship an additional '''mysqld''' binary called '''mysqld-akonadi''' which has '''AppArmor''' set up correctly. If that's the case on your system and you see this problem nevertheless, there are two possible reasons:
* '''Akonadi''' still uses '''mysqld''' instead of '''mysqld-akonadi'''. You can change that in <menuchoice>Systemsettings -> Advanced -> Akonadi -> Server configuration</menuchoice>.
* '''AppArmor''' is not setup correctly for '''mysqld-akonadi''' either. Try running the "aa-complain" command noted above with '''mysqld-akonadi''' instead of '''mysqld'''. 

<!--T:54-->
---

You will also experience this problem if you are running an encrypted home directory using encryptfs combined with '''AppArmor''' as the '''Akonadi apparmor''' profile currently does not account for an ecrypted home (common with ''Ubuntu Jaunty'' users).  Error messages with include:
* dmesg produces:
{{output|1=ecryptfs_do_create: Failure to create dentry in lower fs; rc = [-13]
ecryptfs_create: Failed to create file inlower filesystem}}
* Akonadi will list the following errors:
{{output|1=Akonadi server process not registered at D-Bus}}

The fix is to edit the following file "/etc/apparmor.d/usr.sbin.mysqld-akonadi".
Below the line:
{{output|1=@{HOME}/.local/share/akonadi/** rwk,}}
Add a new line:
{{input|1=@{HOME}/.Private/** rwk,}}

Restart '''apparmor''' and restart '''akonadi'''.

=== Missing Prerequisite ===

To use '''Akonadi''' you need to have the following packages installed (names might differ depending on your distribution):

* The ''MySQL server'' (called '''mysql''' on '''openSUSE''')
* The ''Qt4 MySQL plugin'' (called ''libqt4-sql-mysql'' on ''openSUSE'')

If you compile Qt4 yourself, make sure to tell the configure script to build in MySQL support by passing it the following option:
{{input|1=-plugin-sql-mysql}}
If "configure" cannot locate the necessary MySQL client code (i.e, says "MySQL support cannot be enabled due to functionality tests") then ensure that the corresponding package is installed (typically called ''[lib]mysql[client]-dev[el]''). Also, depending on the install location of the MySQL headers, additional parameters to "configure" might be needed (eg. "-I /usr/include/mysql" on ''OpenSuse'').

If you get the Qt4 direct from ''Nokia'', such as a download of <code>qt-sdk-linux-x86_64-opensource-2009.05.bin</code>, you will ( by the command "akonadictl start") get an error at Test 1:

<!--T:99-->
{{output|1=Database driver not found.
Details: The QtSQL driver 'QMYSQL' is required by your current Akonadi server configuration.
The following drivers are installed: QSQLITE.
Make sure the required driver is installed.}}

The driver you need is ''libqsqlmysql.so''

Unfortunately this driver is not part of the distribution (until january 2010).
You need to compile the source. Download the following file:
{{input|1=qt-everywhere-opensource-src-4.6.0.tar.bz}}

Then ''configure'' and ''make'' as above. But the ''make install'' doesn't copy the driver. So you have to copy it by yourself:
{{input|1=cp <qt-src-dir>/qt-everywhere-opensource-src-4.6.0/plugins/sqldrivers/libqsqlmysql.so /usr/local/bin/sqldrivers/}}
'''But''' the Revision '''4.6.1''', such as qt-sdk-linux-x86_64-opensource-2010.xx.bin has the driver you needed.
'''But''' it might be necessary to bind again the ''libqsqlmysql.so'' if the ''libmysqlclient.so'' has changed to a newer version.

=== Environment Setup ===

The '''Akonadi''' server searches for '''Akonadi''' agents and resources in the paths defined in the ''XDG_DATA_DIRS'' environment variable. If '''Akonadi''' complains about not finding agents or resources, check if this variable is set correctly. Also keep in mind that even if set in a current console session, it might not have been set when starting the server. Starting the server manually in the current console session excludes this cause.

=== mysqld: unknown variable 'innodb_file_per_table=1' === <!--T:69-->

If the MySQL server log contains the following error, then your MySQL server was built without the InnoDB support which is required by '''Akonadi''' or '''InnoDB''' needs to be loaded in your ''mysql.conf'' file:
{{output|1=[ERROR] /usr/libexec/mysqld: unknown variable 'innodb_file_per_table=1'
[ERROR] Aborting}}

Try adding:

<!--T:100-->
{{input|1=#sql_mode=strict_trans_tables <- Add underneath this line
#plugins
plugin_dir=usr/lib/mysql/plugin < - This may be a different path
plugin-load=ha_innodb.so}}
===Table 'mysql. servers' doesn't exist===

If MySQL server log contains the following error, then, most probably, you don't have your MySQL configuration file in place:

<!--T:102-->
{{output|1=[ERROR] Can't open and lock privilege tables: Table 'mysql.servers' doesn't exist
[ERROR] Cannot open mysql.db
[ERROR] Cannot open mysql.user
[ERROR] Cannot open mysql.event}}

Copy it from ''/usr/share/config/akonadi/mysql-global.conf'' into ''~/.config/akonadi/mysql-local.conf''. (For ''debian'' and ''openSuSE'' users the file is located in ''/etc/akonadi/mysql-global.conf''). Then open it and uncomment the line '''sql_mode=strict_trans_tables'''. After that, you may get the following errors:

<!--T:104-->
{{output|1=[ERROR] Plugin 'InnoDB' init function returned error.
[ERROR] Plugin 'InnoDB' registration as a STORAGE ENGINE failed.
[ERROR] Unknown/unsupported table type: innodb
[ERROR] Aborting}}

If so, then in the same file find the line that starts just like the one above (which you have uncommented), but has additional parameters, separated by commas (something like '''sql_mode=strict_trans_tables,strict_all_tables, ...etc'''). Comment the shorter ''sql_mode=...'' line and uncomment the longer one.

On ''openSUSE 11.2'' running the following command will fix this problem:

      <!--T:106-->
{{input|1=mysql_install_db --datadir=$HOME/.local/share/akonadi/db_data/}}

For ''Archlinux'':

{{input|1=mysql_install_db --datadir=$HOME/.local/share/akonadi/db_data/ --basedir=/usr}}

=== Kubuntu 10.04 (Lucid Lynx) Upgrade ===

This is a summary of other entries here for those upgrading from ''Kubuntu 9.10'' to 10.04 who may have been using a personal package archive (PPA) for KDE 4.3 for bug fixes.

Install missing prerequisites.  Remove previous '''akonadi''' cache.  Start the '''akonadi''' service.  Install the database.  Upgrade the database.  Stop and restart the '''akonadi''' service.
{{input|1=sudo apt-get install virtuoso-server mysql-server-5.1
rm -r $HOME/.local/share/akonadi
akonadictl start
mysql_install_db --datadir=$HOME/.local/share/akonadi/db_data/
mysql_upgrade --socket=$HOME/.local/share/akonadi/db_misc/mysql.socket
akonadictl stop
akonadictl start}}

The mysql_install_db command above will report something like the following, which you can safely ignore:

<!--T:108-->
{{output|1=Installing MySQL system tables...
100501 18:04:30 [Warning] Can't create test file 
/home/[userid]/.local/share/akonadi/db_data/[hostname].lower-test}}

Reference:
[http://forum.kde.org/viewtopic.php?f=20&t=79717 forum.kde.org Akonadi 1.2.1 - some issues]

=== KAddressBook upgrade ===

In addition to the ''Kubuntu 10.04'' remedy above, problems trying to add a ''Vcard directory'' may require the following command while '''Akonadi''' is not running:
{{input|1=rm -rf $HOME/.config/akonadi}}

=== Can't initialize character set latin1 ===

If you get the following error when starting Akonadi, then you are probably using a MySQL server which has a version > 5.1.42:

<!--T:84-->
{{output|1=Character set 'latin1' is not a compiled character set and is not specified in the '/usr/share/mysql/charsets/Index.xml' file
Nepomuk QueryServer interface not available!
Connecting to deprecated signal
QDBusConnectionInterface::serviceOwnerChanged(QString,QString,QString)
DataStore::unhideAllPimItems()
Character set 'latin1' is not a compiled character set and is not specified in
the '/usr/share/mysql/charsets/Index.xml' file
Database error: Cannot open database.
Last driver error: "QMYSQL: Unable to connect"
Last database error: "Can't initialize character set latin1 (path:
/usr/share/mysql/charsets/)"
Database error: Cannot open database.
Last driver error: "QMYSQL: Unable to connect"
Last database error: "Can't initialize character set latin1 (path:
/usr/share/mysql/charsets/)"}}

There is a known regression in MySQL 5.1.43 and 5.1.44 which prevents MySQL from starting. 

See [http://bugs.kde.org/226960 the bug report] for more details.


=== Restarting after a previous error ===

If you had problems starting '''Akonadi''' and fixed those (such as a missing package or the '''Apparmor''' problem) make sure that the '''Akonadi''' server is completely shut down before trying to start it again, by calling on the command line:
{{input|1=akonadictl stop}}
You can confirm that it was indeed shut down completely by running:
{{input|1=akonadictl status}}

Under some circumstances the '''Akonadi''' server can be stuck in a partially running state after a failure which will prevent the next attempt to start it to fail as well. Please file a bug report if you run into this problem including the self-test report of the initial problem.

=== The so-called "Gentoo-Assert" ===

That's an especially nasty problem that so far only affects users of source-based distributions, most prominently ''Gentoo''. It is named after MySQL assertions like the following example and is most likely caused by a MySQL protocol mismatch between the MySQL server and the client library or the Qt MySQL driver.

<!--T:92-->
{{output|1=akonadiserver: libmysql.c:4301: setup_one_fetch_function: Assertion
`param->buffer_length != 0' failed.}}

It is extremely hard to diagnose as the assertion mentioned above is only triggered sometimes. Instead you'll get a wide range of weird symptoms:
* ASAP protocol logs show successful creation of objects which are supposedly no longer available when the next commands access them again.
* SQL protocol logs show INSERT or UPDATE commands with values that mismatch the corresponding column types and nevertheless succeed.
* SQL protocol logs showing large apparently random record ids which are nevertheless considered valid.

References:
* http://forum.kde.org/viewtopic.php?f=20&t=61738
* http://bugs.gentoo.org/show_bug.cgi?id=267513
* https://bugs.kde.org/202623 (contains a possible solution)
* http://bbs.archlinux.org/viewtopic.php?id=78358

Possible solution: Rebuild the Qt MySQL driver after upgrading MySQL (which most likely caused this problem in the first place).

=== To reset nepomuk and the akonadi system in KMail 2 === 

Be warned that you should not follow this advice, without backing up your data. 

After the introduction  of KMail 2 in kdepim, since KDE SC 4.6.x, in order to search in emails and to get addressbooks, it is necessary to set <menuchoice>System Settings -> Desktop Search -> Enable Nepomuk Sematic Desktop </menuchoice> enabled, and check the box <menuchoice>Enable Email Indexer</menuchoice>. 

If virtuoso-t occupies almost 100% of CPU cores and the system is nearly frozen, it may be a good idea to reset all.

To do the big reset you need :
{{Warning|1=This will initialize all your Kontact and KDE PIM data customization, but not remove emails data, akonadi resources (like email accounts, address books ), KMail Identities, filters and expired mail folders.  However, be warned that you will lost much customization information, including ratings and other metadata.  Also there is some risk here, because this reconstruction of data has bugs that may make you lose data.}}

{{Input|1=akonadictl stop
rm -rf  ~/.local/share/akonadi/db_data/* 
akonadictl start 
# we should also clean KDE temporary folders before start KMail
rm -rf /var/tmp/kdecache-$USER /tmp/ksocket-$USER /tmp/kde-$USER
}}

You need to check <menuchoice> Settings -> Configure KMail -> Identities</menuchoice> to see whether the Sent folder is correct.  Some of mine were not.

Check <menuchoice> Settings -> Configure KMail -> Accounts </menuchoice> settings and check whether the incoming folder is correct.  Some of mine were not. 

Check all filters, before pulling some email.  I advise disabling all filters because there may be many folders incorrect or missing. 

Also important is that if you have an "expired folder", check all folders to see if the receiving folder is correctly set.  If you have <menuchoice>Delete permanently</menuchoice> checked you may lose important emails because expiring worked with the wrong folder.

In each <menuchoice> folder's context menu -> Folder Properties </menuchoice> check Identities, as the associated identity may also be changed or lost in any folder.   

After this we are ready to [[Special:myLanguage/Akonadi_4.4/Troubleshooting#You experience long delays when sending mail|clean up Nepomuk data]] before enabling Nepomuk Semantic. 

After all is cleaned , if you aren't able to read any emails, you should logout and login KDE session again to reinitialize all processes .
