Description Chris 2021-05-02 13:10:52 UTC

Application: plasma-discover (5.12.8)

Qt Version: 5.9.5
Frameworks Version: 5.44.0
Operating System: Linux 4.15.0-142-generic x86_64
Distribution: Ubuntu 18.04.5 LTS

-- Information about the crash:
- What I was doing when the application crashed:

I saw the icon telling me there were updates available, so I clicked on it.  This reveals the usual dropdown, telling me I have 17 packages to update, so I click "Update" and almost immediately the app crashes.  I am also able to cause the crash by launching the app from Application Launcher.

The crash can be reproduced every time.

-- Backtrace:
Application: Discover (plasma-discover), signal: Aborted
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

> Application: plasma-discover (5.12.8)
This version is no longer supported, and Kubuntu 18.04 is EOL. I would recommend upgrading to Kubuntu 20.04 which will get you Plasma 5.18, or Kubuntu 21.04 which will get you Plasma 5.21.
