Description Patrick Silva 2018-10-28 12:11:37 UTC

STEPS TO REPRODUCE
1. install some app via flathub/flatpak
2. search for the app just installed in the launcher, right click its entry, select "Edit application..." (properties window shows up)
3. click "Application" tab, edit "Name" field to "AppName (flatpak)", click "Ok" button
4. uninstall the flatpak installed in the step 1 via Discover or konsole

OBSERVED RESULT
the entry of the uninstalled flatpak remains in the apps launcher,
no matter if the launcher is kicker, kickoff or dashboard.

EXPECTED RESULT
the entry of the uninstalled flatpak should be removed from the launcher.

Comment 2 Rex Dieter 2019-02-11 04:28:48 UTC

One possible workaround would be for the "Edit" operation to add a
TryExec=
key to match Exec= , so that it won't be shown if the target executable no longer exists.

Otherwise, I suspect there's not much that can be done.

We can't even do that automatically, Exec could be a non-trivial command with arguments whereas TryExec is a path. 

There's not much we can do. Sorry.
