How to remove LibreOffice installed with Lubuntu 20.04

Solution 1:

Basically, it's apt purge libreoffice-common.

You should be able to get almost full list of related packages with dpkg -S /usr/lib/libreoffice. At first glance it looks like all of them are safe to apt purge. List of packages that were first "level" for Lubuntu:

$ apt depends lubuntu-desktop | grep libreoffice

  Recommends: libreoffice-calc
  Recommends: libreoffice-gtk3
  Recommends: libreoffice-impress
  Recommends: libreoffice-qt5
  Recommends: libreoffice-style-breeze
  Recommends: libreoffice-writer

Solution 2:

Firstly I'll apologize for the errors I missed in my answer on Easy fix for LibreOffice Impress font problems on Lubutu 20.04?. I have corrected it.

To remove the additional packages you need to run

sudo apt remove libreoffice-core libreoffice-common libreoffice-style-breeze
sudo apt autoremove

I'm not removing every package... via command hoping for the rest being removed when the autoremove is performed. I'd executed that later because they were left, but had failed to copy those packages into my prior answer, for which I'll apologize again. Sorry.
