Description Mark Stanton 2021-05-18 07:27:01 UTC

Application: apper (1.0.0)

Qt Version: 5.15.2
Frameworks Version: 5.81.0
Operating System: Linux 5.11.19-300.fc34.x86_64 x86_64
Windowing System: X11
Drkonqi Version: 5.21.5
Distribution: "Fedora release 34 (Thirty Four)"

-- Information about the crash:
Running apper for the first time since F34 upgrade. Apper simply crashed.

Update appears to have finished. From previous experience I would expect that what was either happening or about to happen was a further check for applicable updates

The reporter is unsure if this crash is reproducible.

-- Backtrace:
Application: Apper (apper), signal: Segmentation fault

Comment 3 Christoph Cullmann 2025-06-10 18:22:47 UTC

This project is unfortunately no longer maintained.

If a new maintainer wants to step up and take care, the project is archived here:

https://invent.kde.org/system/apper

You can just clone it in your private namespace on invent.kde.org and if you have started to work on it and fixed/implemented something get it reviewed and the project unarchived.

Sorry for the inconveniences.
