Bug 495354

SUMMARY
I am running Neon User edition since a few years back. When I first installed it, I had Plasma 5 and I have since kept up to date and am now on Plasma 6.2.2. It seems some PIM packages from the Plasma 5 generation have not been deleted when updating to Plasma 6, and for a few of them, I can neither uninstall them nor install the updates that Discover reports are available.

When I try to uninstall the libkpim5* packages via the Installed section in Discover, nothing happens and no error message is shown. I have also tried uninstalling them via synaptic, but this gives an error for the three specific packages libkpim5akonadimime-data, libkpim5libkleo-data and libkpim5mailtransport-data.

I have also tried to use the terminal to either uninstall or update the packages, with results shown below.

I previously reported an issue in bug 495197 and was advised to uninstall the packages, but as described here I can neither uninstall nor update the three packages mentioned above.

STEPS TO REPRODUCE
1. Try to uninstall or update the aforementioned packages
2. Error messages in both cases

OBSERVED RESULT

When I try to use sudo apt autoremove, I get the following:

Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
 libkpim5akonadimime5 : Depends: libkpim5akonadimime-data (= 4:23.08.5-0ubuntu3) but it is not installed
 libkpim5libkleo5 : Depends: libkpim5libkleo-data (= 4:23.08.5-0ubuntu3) but it is not installed
 libkpim5mailtransport5 : Depends: libkpim5mailtransport-data (= 23.08.5-0ubuntu3) but it is not installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

EXPECTED RESULT

I want to either uninstall the packages or update them so they are no longer showing as having available updates in Discover. I suppose apt should have some list of installed packages somewhere and that if the package names are removed from there, Discover might no longer report updates for those packages. The packages are probably not used any more in Plasma 6 and they probably also don't use a lot of disk space, so simply keeping whatever is currently installed and just removing the names of these packages from the list that Discover finds updates for should solve the issue that these updates are reported to exist but cannot be installed.
