snapd fails after Kubuntu 24.04 install

[Hadmut Danisch]

Hi,

I was just installing a notebook with Kubuntu 24.04 install (which recently worked well with 24.04 beta, but I replaced the SSD and wanted to reinstall).

Problem:

snapd doesn't run properly, issues

last-occurrence: heute um 22:43 EEST
warning: |
  seeding failed with: cannot use snap "krita": default provider
  "kf5-5-113-qt-5-15-11-core22" or any alternative provider for content
  "kf5-5-113-qt-5-15-11-core22-all" is missing. This indicates an error in your
  distribution, please see https://forum.snapcraft.io/t/16341 for more
  information.

and I cannot even run ubuntu-bug on that machine, it says

error running snapctl: cannot invoke snapctl operation commands from outside of a snap

but my guess is, that the problem is not the software or installation, but some seed file, which is downloaded from whereever.

Systemd service snapd.seeded.service is still running (and obviously waiting)

so it looks rather as a problem of the snap online services than of the Kubuntu installation.
