Description Piotr Mierzwinski 2020-11-04 11:32:22 UTC

SUMMARY
I tried to find installed package calling kvantum. Discover returned me only useless, not related packages.
In my system (Arch) this package calling kvantum-qt5, but also putting such name returns nothing interested. I know that packages is installed, because pamac returns me correct information.

The same I also tested in "KDE Neon" (with recent updates, so today, 12:15. Here I found Plasma 5.20.80 and KF-5.76.0). Here package calls qt5-style-kvantum. Package manager Synaptic returned me correct information, whilst Discover returned useless, not usable information about some packages.

After that I tried to find another applications/packages what I have installed, and again without success. I tried with: gdb, kdevelop, konsole, discover, kwrite, kate. Every time, whatever I put here then after pressing Enter I can see the same list of packages.

STEPS TO REPRODUCE
1. Run Discover and select "Installed"
2. Put any name of installed application/package. I tested with kvantum, gdb, kdevelop, konsole, discover, kwrite, kate
3. Check result in view "Installed"

OBSERVED RESULT
Found nothing, or actually is shown some list of packages not related with search template.

EXPECTED RESULT
All packages matching to search template like showed in other package managers (pamac, octopi, Synaptic).

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: YES
(available in About System)
KDE Plasma Version: 5.20.2
KDE Frameworks Version: 5.75.0
Qt Version: 5.15.1

ADDITIONAL INFORMATION

Comment 1 Nate Graham 2020-11-04 18:21:17 UTC

Discover isn't a package manager. It's used for installing and managing apps and user-facing resources, not packages.

That said, the installed page being broken is definitely a bug. I can reproduce. This used to work but it looks like it must have broken recently.

Comment 2 cassim2972 2020-12-05 14:39:00 UTC

i am receiving aborted due to failure error when i try to update all applications or remove single application in discover.

Comment 3 David Edmundson 2021-01-09 19:09:46 UTC

PackageKitBackend::search doesn't check filter.search if filter.state == installed.

We were giving all of them and the proxy isn't smart enough to do the
