Again, I'm guessing, but maybe you've ended up with parts from two installations.
In a terminal, run these commands
(That's a lower case l, not a one.)Code:dpkg -l | grep office dpkg -l | grep ooobasis dpkg -l | grep libre
These will give an idea as to what's installed.
The last command should show nothing related to libreoffice (though it might show some other packages that have nothing to do with it).
The other two will show you which OpenOffice packages are installed.
