hm, rerun with updated install script and it seems it was able to recover the containers. Not sure if using old install script was the culprit

I have literally never seen that error from containerd. It’s trying to access a registry while creating the snapshotter during startup?
and it got a 404 from it?
m
I’m using internal registry and basically block access to dockerhub, etc. Maybe the mirror configuration somehow gets messed up during upgrade
c
are you also using one of the non-standard snapshotters? btrfs or stargz or something?
I would probably go create an issue on the containerd GH repo if you see it again.
m
stargz yes
c
yeah, probably a bug in that then.
m
hmm
c
I would grab the full containerd logs and create an issue
I don’t think hardly anyone uses stargz
so they’d probably appreciate the report

Also if it makes your life easier (kinda unrelated) rancher has a tool for upgrading k3s clusters in an automated fashion: https://github.com/rancher/system-upgrade-controller

@bulky-sunset-52084 Yes, I tried it but couldn’t find working configuration
