"Debian Bug report logs - #851175
plasma-workspace - All shell packages missing. This is an installation
issue, please contact your distribution - missing dependency on
plasma-desktop-data" I got hit with this one "All shell packages
missing." while updating a Buster install today, it started with dpkg
not being able to overwrite package "desktop-profiles" so instead of
doing a force install I chose to purge the package and completed the
update then reinstalled desktop-profiles, on reboot, after login is when
I got hit with "All shell packages missing." and plasma would not start
and it seems to be ambiguous from what I get searching the net, in my
case the problem was package "desktop-profiles" being installed and
purging desktop-profiles solved the problem and Plasma starts fine now.
Why would "desktop-profiles" being installed keep plasma from starting?
Upgrade-system said the system was completely updated and clean with no
orphaned packages before I rebooted.
