Answer 1

By investigating with Synaptic and trial & error method I came up with the solution:

sudo apt-get install libreoffice-style-tango libreoffice-gtk libreoffice-gtk3

I have no idea why these packages were missing. I hope this helps someone.

Answer 2

sudo apt install --no-install-recommends libreoffice-gtk3

Just install what is needed to make your LibreOffice beautiful again.

Works on (X|L)Ubuntu 18.04+.

Answer 3

sudo apt-get install libreoffice-gtk

Also upper command line works for lubuntu (LXDE). For example with flat gtk theme 'victory' and 'papirus' icons LibreOffice looks great.

Answer 4

The minimum requirements to get the correct look for LibreOffice in Xubuntu is libreoffice-gtk along with either libreoffice-style-tango or libreoffice-style-human
