Unable to Update to Microk8s v 1.32

[HeIp]

Summary

I had just started using microk8s yesterday - latest version is MicroK8s v1.31.3 revision 7456
After seeing a whole issue on how there been issue for crashlooping, file configs, etcs detailed on #4361 I see that a lot would get resolved in v1.32+ however,
running command "sudo snap refresh microk8s " leads to snap saying the latest version is MicroK8s v1.31.3 revision 7456.

What Should Happen Instead?

I am expecting to update microk8s to 1.32+
to remediate the following issues :

Reproduction Steps

1. sudo snap refresh microk8s
2. reports you are on latest - snap "microk8s" has no updates available

Hey @HeIp,

snap refresh command without any specific channel specified would try to refresh to the latest revision in the channel the snap is currently tracking, which means you'd only get 1.31.x updates. You can see your tracking channel in snap list. Can you try sudo snap refresh microk8s --channel 1.32/stable to update to 1.32?

sudo snap refresh microk8s --channel 1.32/stable

microk8s (1.32/stable) v1.32.0 from Canonical✓ refreshed
Seems it was updated
But is now unable to start ...?

Hi @HeIp! After doing a snap refresh it might take some time (hopefully a couple of seconds) before your cluster is responsive again. That's because the processes are being restarted (that includes API server). I suspect the errors that you're seeing are probably because the API server is not yet fully restarted. Have you tried again after a while?

Hey @HomayoonAlimohammadi , seems to be pretty consistent :

The command microk8s status --wait-ready also seems to just hang
