If you actually want to remove libreoffice entirely you could use the following command which should remove them all (as root)
I haven't tested this command exactly but I used it a short wile back when cleaning a system of unwanted packages. You could also add the -s switch to simulate what it does without actually changing anything (a good way to ensure purging a package won't remove something you want to keep.
Code: Select all
apt -s remove --purge libreoffice*
No need for root for this as it changes nothing.
EDIT:
You could also change the remove to autoremove to clear orphaned dependencies too (in either of the two commands)
