Knowing no better, I ran the ‘automatic’ update and install commands with my eyes closed.
apt-get update apt-get upgrade
Reading other posts on this subject brings me to this command;
zgrep 'install ' /var/log/dpkg.log* | sort | cut -f1,2,4 -d' '
This indeed shows that have installed some Xserver components.
Using CRTL+ALT+F3, I am still able to access a terminal.
The GUI that is displayed has no ‘start button/menu’ and seems to just be a blue background.
This installation is a VM and I have a snapshot. I intend to roll back to the snapshot (before trying again).
I do have the resources necessary to run a GUI – but had hoped not to.
when running apt-get update, is there a simple way of identifying updates that may cause a GUI (or in this case, incomplete parts of a GUI) to be installed?
Of course, I will pay more attention and not install packages that are not “…./ubuntu focal” (other than those for packages I am using and know to be non-Gui).
I know I have a lot of manual reading to do – but other than ‘don’t blindly click around’ is there any other useful advice the community can offer?
