Zorin Apperance was not working. So I searched a fix on this forum and found this thread.
I ran these commands
sudo apt update
sudo apt install zorin-os-desktop
sudo apt full-upgrade
It fixed the problem I had with the Zorin appearance. Now it opens.
I see a difference before and after the upgrades.
So I doubt that I'm no longer using the lite version.
How to check which version I have now ?
