Short version: "apt remove gdb-minimal" seems to have also removed
plasma-desktop + a bunch of related packages.
Curious if there are any good debugging tips for figuring out what
happened here.
Or maybe I'm missing something obvious about how apt works, and this
is expected behavior?
Yesterday, I was trying to use gdb, and realized I had gdb-minimal
installed instead of the regular gdb package.
To fix this, I first ran "apt remove gdb-minimal".
My assumption was that I then would have to run "apt install gdb".
But turns out that invoking "gdb" after running "apt remove
gdb-minimal", I had the full version of gdb installed.
I didn't think more about it, went on using gdb and later shut down
the computer.
When I booted it today, a different display manager than what I
usually have was shown. Switching to a different pseudoterminal and
checking "/var/log/apt/history.log" showed that when I had removed
gdb-minimal, for some reason plasma-desktop and some other packages
had also been removed.
This is the entry I saw:

(Looks like this is where regular gdb got installed too, so I didn't
actually have it, it just got autoinstalled when I removed
gdb-minimal?)
(Also, probably this info got printed when I ran "apt remove
gdb-minimal", and I was not paying attention.)
To fix it, I ran this command and rebooted with "systemctl reboot",
which seems to have worked fine. Now I'm back in the expected desktop
environment.
apt install kinfocenter plasma-workspace plasma-widgets-addons
plasma-workspace-wayland sddm-theme-breeze sddm-theme-debian-breeze
kde-plasma-desktop plasma-desktop
Looking back in history.log, the only other references to gdb-minimal
and plasma-desktop I could find was near the top of the file (15th
entry):

Install: ...
I've cut off the "Install :" part, because it continues for more than
a screen. It contains both the kde-packages which were gone from my
system, and gdb-minimal.
I assume that this is from when I ran the debian installer on monday
(fresh install).
I appreciate any input, thanks in advance.
