Description Kamil Páral 2021-10-20 07:15:19 UTC 
Description of problem:
In Discover, if you install an app, you can't uninstall it shortly afterwards, you'll only see "Package not found" error. Similarly, if you uninstall an app, you can't install it again, because of the same error.

This prevents people from:
1. Quickly trying out different apps, e.g. when looking for a good image editor. "This one? No. This one? No. This one? Yes, I like it, I'll keep it."
2. Reinstalling an app if they experience some troubles with it.

Closing and reopening Discover makes Discover recover from the problem, and you can then remove or install the app that previously was producing the errors.

Version-Release number of selected component (if applicable):
plasma-discover-5.23.0-3.fc35
PackageKit-1.2.4-2.fc35

How reproducible:
always

Steps to Reproduce:
1. install an RPM app
2. try to remove it, it fails with "Package not found"
3. restart Discover
4. remove the app, now it works
5. try to install the app again, it fails again with "Package not found"

Proposing for a blocker discussion.
Comment 5 Kamil Páral 2021-10-20 08:01:40 UTC 
This doesn't seem to be a recent regression in the last-minute fixes we did for plasma-discover, because 5.23.0-1.fc35 also exhibits this bug.
Comment 6 Adam Williamson 2021-10-20 16:36:04 UTC 
Does F34 behave the same?

> Does F34 behave the same?

Yes, F34 clean KDE Live install behaves the same.
Comment 8 Ben Cotton 2021-10-21 18:34:58 UTC 
In today's Go/No-Go meeting we agreed: It is functional enough to ship and fix in an update, but we'd like to have it in the release if a fix is available and we slip

Comment 10 Aleix Pol 2021-10-21 21:32:31 UTC 
I spent some time looking into this one yesterday. It's not clear to me if it's a packagekit dnf backend but or Discover's, I guess I better see if we can workaround it from within Discover anyway.

Problem is that we are using the package id that the install transaction gives us as the new pkgid, I can change it to issue a new resolve query instead.
