LibreOffice (Microsoft Office/Word Substitute)

(Optional) If you want a more up to date version of libreoffice (v5.4) vs the LTS version (v5.1), use the following ppa.

sudo add-apt-repository ppa:libreoffice/ppa
sudo apt update

Otherwise, install the gtk3 version (since it's designed for it) and the breeze style. We need the Calibri and Cambria replacement fonts otherwise Microsoft Office files will look weird. Lastly we should clean the icon cache just in case.

sudo apt install -y libreoffice libreoffice-gtk3 libreoffice-style-*
sudo apt install -y fonts-crosextra-carlito fonts-crosextra-caladea
rm ~/.cache/icon-cache.kcache
