I have both libreoffice 6.0 and 6.2 installed.in Ubuntu 18.04.2 LTS When I look into synaptic installer I can't find the 6.2 version but it is definitively there. In the ubuntu software I can find both version but any attempt to remove 6.0 from there fails. Or more acurately I can remove them using the remove button and seconds later they are back. Also tried:
sudo apt-get remove --purge libreoffice6.0* Reading package lists... Done Building dependency tree
Reading state information... Done E: Unable to locate package libreoffice6.0* E: Couldn't find any package by glob 'libreoffice6.0*' E: Couldn't find any package by regex 'libreoffice6.0*'
