The pc-kernel snap seems to be a bit older than the deb distribution:
24/stable: 6.8.0-40.40
24.04 (deb): 6.8.0-44.44
Also don’t see a beta/candidate/edge branch for the 6.11 RCs, not sure if that’s intended and should only use debs for testing 24.10
For the record, here’s the link to the kernel release schedule:
https://kernel.ubuntu.com/
And all the gory details about all kernel packages in flight for all open/active cycles:
https://kernel.ubuntu.com/reports/kernel-stable-board/
In general, the snaps gate the debs, meaning the debs get only released to -updates after the snaps have been promoted to stable. This should happen automatically but we had some issues and had to hold back snaps (but didn’t want to block the release of debs) so in this particular case the snap had to be promoted manually. Which happened yesterday.
We are not yet building 6.11 kernel snaps, the launchpad builders are not yet ready for that and there is no urgent need.
