For some reason Discover doesn't start on Kubuntu for me. This has started happening starting a few weeks ago. I can run apt-get commands just fine from the console with no warnings or errors. There is no output on the console if I run the command plasma-discover --mode update in Konsole.

Also if I launch plasma-discover --mode update under another account, say root using sudo, it starts up properly.

How can I debug this further? I suspect some config file is corrupted but I cannot figure out which one.

  • So, no error when running plasma-discover? – cipricus Jun 08 '23 at 12:40
  • Correct, I am stumped. – proteus Jun 08 '23 at 18:54
  • Same issue here with Kubuntu 24.04. Only launching with sudo makes no difference. – rustyx May 10 '24 at 13:36
  • Same issue on Kubuntu 24.04, with sudo I get this errors:

  • This worked for me: sudo apt purge plasma-discover-backend-snap based on this post: https://www.kubuntuforums.net/forum/currently-supported-releases/kubuntu-24-04-nitpick-noble-lts/software-support-bg/679024-plasma-discover-not-starting?p=679282#post679282 – Phoca May 23 '24 at 14:55
