Bug ID: 466703
Summary: Multiple Problems: KDebugSettings is necessary to
debug Discover, however Discover in Ubuntu Studio does
not support installing it.
Classification: Applications
Product: kdebugsettings
Version: unspecified
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: mon...@kde.org

SUMMARY
***
I would like to help provide a back trace with debug symbols for Discover
Notifier's segmentation crashes.
However, I seem to be caught in a catch-22 situation, that is the consistently
failing app, Discover, is the one needed for installing kdebugssettings to
debug Discover Notifier, which fails to install kdebugssettings which are ....
STEPS TO REPRODUCE
Note: I am afraid I am not good enough at command line work to understand
sufficiently the instructions I found on line for creating a segmentation fault
in an app. So, I have not attempted to reproduce this by that means. If
supplied a precise step by step example to follow I would have a better
chance.
However, Discover Notification and some other apps do fail without meaningful
backtraces about every two days, so it reproduces itself in a fairly consistent
fashion.
In that case:
1. When Discover Notifier crashes, note the kcrash reports it cannot supply a
backtrace and recommends downloading and installing debug tools.
2. Navigate to https://apps.kde.org/kdebugsettings/ [I am not a developer so
this seemed to be what is available for users.]
3. Note the [Install on Linux] button only works with Discover which is the app
manager for Ubuntu Studio,
4. Click [Install on Linux]
5. "Open with ... -- Portal" only shows a button titled [Software]
6. Click [Software], Note that the pointer shows it is a link, but the app
"Software" does not open.
7. Click [Discover] in the line "More applications are available in
[Discover]."
8. The GNOME application manager opens with the message "Failed to install: not
supported."
9. Search in both the discover and GNOME package managers for both
"kdebugssettings" or "x-scheme-handler/appstream" as the name is shown in the
Open with portal.
10. Receive "not found" messages for each.
OBSERVED RESULT[S]
1. Kcrash consistently cannot supply a meaningful backtrace beyond
----------------------------------------------------------------
Application: DiscoverNotifier (5.24.7)
Qt Version: 5.15.3
Frameworks Version: 5.92.0
Operating System: Linux 5.15.0-60-lowlatency x86_64
Windowing System: X11
Distribution: Ubuntu 22.04.2 LTS
DrKonqi: 5.24.5 [KCrashBackend]
The reporter is unsure if this crash is reproducible.
-- Backtrace:
A useful backtrace could not be generated
Report to https://bugs.kde.org/
------------------------------------------------------------------------------------------------------
2. The Install on Linux button in
https://apps.kde.org/kdebugsettings/
which is supposed to open Discover opens "Open with ... -- Portal"
instead.
3. The button titled [Software] does not open an app.
4. The button titled [Discover]" opens the GNOME application manager.
5. The GNOME application manager displays the message "Failed to install: not
supported."
6. The Discover and GNOME package managers return "not found" for searches for
"kdebugssettings" or "x-scheme-handler/appstream"
EXPECTED RESULT
1. Kcrash supplies a meaningful back trace and continues the automatic
reporting procedure.
2. The [Install on Linux] button in
https://apps.kde.org/kdebugsettings/
opens Discover unless the "Open with ... -- Portal" is the correct
app.
3. "Open with ... -- Portal" The button titled [Software] opens an app
capable of installing "kdebugssettings".
4. "Open with ... -- Portal" shows a button titled [Discover] as well as
[Software] or instead of [Software].
5. The current "Open with ... -- Portal" button titled [Discover] opens
Discover.
5. The GNOME application manager should not called in any of the above
cases*
6. The Discover package manager lists "kdebugssettings" or
"x-scheme-handler/appstream" for installation and successfully installs same.

ADDITIONAL INFORMATION
* Unless the GNOME application manager is supposed to be compatible with the
[Install on Linux] button and that would be a separate bug.
If my assumption that kdebugsettings is the appropriate tool is in error,
please advise as to the correct tool and the steps necessary to install and use
it correctly.
Also, If this needs to be separated into more than one bug report. Is there a
way to do so while maintaining the relationships or dependency of one bug on
another.
My apologies to the triage crew. My brain is more attuned to visual physics
than languages and programming
