From KDE UserBase Wiki

Introdução

Esta página evidencia principalmente a solução de problemas com o Akonadi, uma vez que existem falhas inevitáveis ​​nas fases iniciais de migração. Para muitas pessoas, os primeiros sinais de atividade do Akonadi estará no KDE SC 4.4, e muitas irão ficar confusos com ele. Para uma breve descrição do propósito do Akonadi, veja o item neste glossário. Você também vai encontrar links úteis para posterior leitura. Resolvidos os inevitáveis problemas iniciais, o Akonadi demostrará o seu poder para muitos aplicativos.

Entendendo a estrutura

Você pode, é claro, simplesmente usar o Kontact para gerenciar todos os seus livros de endereços, mas se em vez disso você tiver um sistema de backup, por exemplo, você gostará de saber onde seus dados estão e como são trabalhados. A página Akonadi e livro de endereços irá ajudar.

Dicas para solução de problemas

  • Ao relatar problemas com o servidor Akonadi, sempre inclua o relatório de teste automático. Este relatório pode ser obtido a partir da janela que aparece sempre que o servidor Akonadi não for capaz de iniciar com êxito. Você pode encontrar o teste automático no diálogo no kcmmodule que é acessível via:
kcmshell4 kcm_akonadi
  • Iniciar o servidor Akonadi manualmente pela linha de comando pode fornecer-lhe informações adicionais úteis. Isto pode ser feito executando o seguinte comando no terminal:
akonadictl start

Da mesma forma, com este comando o servidor Akonadi pode ser interrompido novamente: 

akonadictl stop

Este comando fornece mais informações úteis: 

akonadictl status

Problemas comuns

O Kontact não inicia e nenhuma mensagem é mostrada

Se o Kontact não iniciar e também não apresentar qualquer mensagem de erro, verifique se o Akonadi está em execução. O Akonadi deveria ser iniciado quando fosse demandado. Se não for o seu caso, você terá que iniciá-lo antes do Kontact se já houve a migração de algum recurso (o mais provável é o KAddressBook). Use o ícone da área de notificação do Akonadi (basta digitar "akonadi" no KRunner) ou digite os comandos no konsole para iniciá-lo.

O Kontact não inicia - versão II

Sabe-se que o Kontact é afetado após uma atualização. Se isto ocorrer, tente iniciar o KMail, o KOrganizer ou qualquer outro aplicativo a partir do KRunner ou do Konsole. Há grandes chances de que funcionem como aplicativos independentes enquanto você tenta identificar o problema. Isto afeta principalmente a versão 4.4.0.

Pasta não encontrada: "/Local"

Algumas pessoas relataram esse erro quando o Kontact não inicia. Em algumas versões anteriores à 4.4 parece haver um erro na migração que está informando ao KMail para procurar as mensagens locais em ~/.local/share/Local, uma pasta que não tinha sido criada. A solução para isso é não tentar corrigi-lo, mas com o KMail/ Kontact fechados, abrir o Console do Akonadi:

  • Use krunner, Alt-F2, ou
  • "akonadiconsole" konsole

Depois remova o recurso que informa ser o correio local. Você pode agora iniciar o Kontact ou o KMail e um novo recurso será criado, direcionando para ~/.local/share/local-mail.

Existem outras pastas novas em ~/.local/share/

Sim. Se o seu livro de endereços foi migrado corretamente, um novo recurso foi criado como ~/.local/share/contacts/

O que são /usr/bin/akonadi_maildir_resource e /usr/bin/akonadi_maildispatcher_agent?

O akonadi_maildir_resource é criado automaticamente pelo akonadi_maildispatcher_agent, enquanto o segundo sempre é iniciado junto com o Servidor Akonadi, já que proporciona as funcionalidades básicas (por exemplo, enviar um e-mail) que são usadas pelos aplicativos de e-mail que são (ou serão) baseados no Akonadi. Portanto, se você for um usuário normal, pode ignorar estes dois aplicativos que estiverem em execução. O recurso gerado automaticamente akonadi_maildir_resource, sempre irá direcionar para ~/.local/share/local-mail/ que é onde serão armazenados os seus e-mails e pastas locais.

Neste momento, com KDE SC 4.4, os e-mails ainda não estão sendo migrados.

Os agentes de indexação do Nepomuk foram desativados

O Kontact está em execução, mas o aviso a seguir é apresentado:

O motivo mais comum para este aviso é que o Nepomuk simplesmente está desativado nas Configurações do Sistema. Tente ativá-lo em Configurações do Sistema: Avançado -> Pesquisa na área de trabalho -> Configurações básicas marcando "Habilitar o ambiente de trabalho semântico do Nepomuk" e clicando em "Aplicar".

Se isto não ajudar (ou se a opção já estava assinalada quando você obteve o erro) e se você já tinha usado previamente versões anteriores do KDE SC 4.4, é possível que seja um problema decorrente de alguma alteração de leiaute do banco de dados (devido a uma atualização da versão 5 para a 6 do servidor de banco de dados Virtuoso; espera-se que as versões de produção do KDE SC 4.4 sejam lançadas com a versão 6 do Virtuoso). Os comandos a seguir devem fazê-lo funcionar novamente: 

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: 

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 System Settings -> Advanced tab -> KDE Resources. 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 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: 

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.

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): 

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 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 

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.

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: 

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: 

aa-complain mysqld

On Kubuntu this is: 

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 Systemsettings -> Advanced -> Akonadi -> Server configuration.
  • AppArmor is not setup correctly for mysqld-akonadi either. Try running the "aa-complain" command noted above with mysqld-akonadi instead of mysqld.

---

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:
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:
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: 

@{HOME}/.local/share/akonadi/** rwk,

Add a new line: 

@{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: 

-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 qt-sdk-linux-x86_64-opensource-2009.05.bin, you will ( by the command "akonadictl start") get an error at Test 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: 

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: 

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'

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: 

[ERROR] /usr/libexec/mysqld: unknown variable 'innodb_file_per_table=1'
[ERROR] Aborting

Try adding: 

#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: 

[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: 

[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: 

mysql_install_db --datadir=$HOME/.local/share/akonadi/db_data/

For Archlinux: 

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. 

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: 

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: 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: 

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: 

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 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: 

akonadictl stop

You can confirm that it was indeed shut down completely by running: 

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. 

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.

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