You can try collecting the installed packages on debian-11 distro into a text file:
(in debian-11 template) $ apt list --installed > debian-11-packs
and then do the same with your current debian-11-minimal one:
(in debian-11-minimal template) $ apt list --installed > debian-11-min-packs
and then either inspect the contents of these two files, or copy these two files into a qube and run a diff command on them:
$ diff debian-11-packs debian-11-min-packs
That way, you can see which packages are absent in the minimal qube, and then install the related ones to your issue.
Possibly unrelated, but when I install GIMP [edit: on a deb11 minimal-derived template] most of the buttons used by the app don’t have icons on them. So I’m faced with toolbars full of Xs. [These are even less useful than the doodles on Micro$haft’s never-to-be-sufficiently-damned “ribbons” (at home I refuse to move past office 2003).]
Why GIMP doesn’t come with its own icons is a mystery to me, but I have no idea how to even BEGIN to figure out what to install to fix this. Googling leads me to people complaining about no link to GIMP or no critter GIMP icon for the app itself, not about the button graphics being gone.
OK, here is another GTK-related issue with vim-gtk, xterm and debian-11-minimal:
Inserted characters are still displayed on screen despite after having deleted them, e.g. with x in normal mode.
vim on debian-11: works vim-gtk on debian-11: works vim on debian-11-minimal: works vim-gtk on debian-11-minimal: does not work
(all vanilla templates)
UTF8 encoding is set both in xterm and vim, which is a solution from other search results.
A central Qubes OS contrib resource for how to install specific apps in minimal templates would be very helpful, wouldn’t it?
