Product: Discover
Version: 5.23.4
Platform: Other
OS: Linux
Status: REPORTED
Severity: critical

Appstream Discover error message
SUMMARY
A bug, presumably related to `rpm-ostree` backend, makes Discover unable to
show applications accessible through Appstream.
STEPS TO REPRODUCE
1. Open Discover
2. Search for Kate editor
OBSERVED RESULT
An error message stating `Could not open appstream://org.kde.kate.desktop`
EXPECTED RESULT
Kate editor showing up in the applications list
SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Fedora Silverblue 35 (Kinoite)
(available in About System)
KDE Plasma Version: 5.23.4
KDE Frameworks Version: 5.89.0
Qt Version: 5.15.2
ADDITIONAL INFORMATION
While it seems the issue is associated with ` OSTree`, another user mentions
that this error could also be associated with the fact the Kinoite doesn't ship
with ` packagekit`:
`this is most likely due to the fact that we don't ship packagekit on Kinoite.`
We did some troubleshooting to try to understand what's happening, here are the
results:
```
$ plasma-discover --application appstream://org.kde.kate
$
```
The above command executes successfully (no error message, no shell error exit
code), but it shows no output whatsoever
```
