Next up for IT 566 is installing LibreOffice. LibreOffice is an Oracle-less fork/update of OpenOffice.
I installed LibreOffice using this method, via apt and a PPA repository.
Update: Feb. 20 Better, more clearly written instructions are at Ubuntu Wiki.
These instructions will remove OpenOffice as well.
Here’s LibreOffice Writer running, also showing LibreOffice in the Ubuntu menu.
Here’s a LibreOffice file association.
