microk8s: Error trying to enable community on MicroK8s v1.27.2

Summary

Error trying to enable community on MicroK8s v1.27.2

I have some VMs on DigitalOcean, and I’ve installed MicroK8s v1.27.2 revision 5372. When I try to run microk8s enable community I get an error: microk8s community ModuleNotFoundError: No module named 'importlib_resources'

What Should Happen Instead?

The community addon should enable, so I can then use community addons.

Reproduction Steps

Consistently reproducible.

Set up 3 VMs on Digital Ocean
Install MicroK8s
Try to enable community: microk8s enable community

This is what shows:

Note that, if I use MicroK8s 1.26, I don’t have a problem - community enables fine.

Hi @angelcervera @jamest-portainer the fix has been backported to 1.27 tracks now, and it is available on the 1.27/edge channel, i.e.

sudo snap refresh microk8s --channel 1.27/edge

And it is currently in progress to be pushed to 1.27/stable (should land in a couple of days)

Hi @neoaggelos, yes, I tried your build and it works.

As follows…

root@ubuntu:~# snap install microk8s --classic
Download snap "microk8s" (5372) from channel "1.27/stable"
[etc.]
Run configure hook of "microk8s" snap if present
[etc.]
microk8s (1.27/stable) v1.27.2 from Canonical✓ installed
