Can you give the output of:

lsb_release -a; uname -a; dpkg -l | egrep 'libre|open' | grep office

Thanks

Maverick is no longer supported in any way. I suggest you remove the Maveric partitions and clean install Precise. Not only is it the latest stable Ubuntu release but it is also LTS, giving support all the way to 2017.
