I was running Ubuntu server and wanted to use a DE, but now I can't uninstall it. There are some problems with sleep settings, where the server will go to sleep because of some packages installed by KDE Plasma. When I try to remove it I get "not installed so not removed"
Here is exactly what I do.
sudo apt purge plasma-desktop:
Reading package lists... Done
Building dependency tree
Reading state information... Done
Package 'plasma-desktop' is not installed, so not removed
0 upgraded, 0 newly installed, 0 to remove and 30 not upgraded.
But then I run sudo apt list plasma:
Listing... Done
plasma-applet-redshift-control/focal 1.0.18+phabricator~2019080100-1 all
plasma-browser-integration/focal-updates,now 5.18.5-0ubuntu0.1 amd64 [residual-config]
plasma-calendar-addons/focal-updates 4:5.18.7-0ubuntu0.1 amd64
plasma-dataengines-addons/focal-updates 4:5.18.7-0ubuntu0.1 amd64
plasma-desktop-data/focal-updates 4:5.18.8-0ubuntu0.1 all
... And even more packages.
Clearly SOMETHING is still installed. How can I get rid of it?
