Bug#1068777: plasma-systemmonitor with the process manager is not installed anymore after upgrading to Debian12
Package: kde-plasma-desktop
Version: 5:142
After upgrading from Debian11/KDE to Debian12, plasma-systemmonitor was not installed. This should definitely be an installed package and I think it is configured to be.
On Debian11, KSysGuard was used. Now there only is KSysguard in "Background Services" which "Launches KSysguard on Ctrl + Escape" and launches systemd->systemmonitor. While this shortcut was kept, ctrl+shift+esc wasn't set anymore so one has to configure it again under "Custom Shortcuts" with command "plasma-systemmonitor".
I checked /var/log/apt/history.log and there it says "plasma-systemmonitor:amd64 (5.27.5-2, automatic)" underneath apt-get full-upgrade in the packages next to "Install: ". However that process exited with "Error: Sub-process /usr/bin/dpkg returned an error code (1)" because of "FATAL ERROR: Both /lib/udev/mtp-probe and /usr/lib/udev/mtp-probe exist." after which I ran "apt --fix-broken install" before running "apt-get full-upgrade" again.
Right after all this (that is upgrading to Debian12) I noticed this package was not installed and installed this specific package.
plasma-systemmonitor, which includes the process manager, should always be installed by default on a new KDE setup as well as when upgrading from the prior Debian version which had KSysguard installed. In addition, the widely known and much used shortcut ctrl+shift+esc should also be there by default and launch plasma-systemmonitor (or alternatively systemmonitor).
