I will try that command, thanks.
And I did do a search before posting, searching for "install desktop" and "reinstall desktop" but did not find anything relevant, with the most relevant being how to install a desktop environment from Synaptic, which, however, is not applicable for me as I do not even have Synaptic.
Do you have a particular thread in mind where this was answered? I would like to see what I should have searched for.
