/dev/kmsg Issue #5

Closed aldycool closed 2 years ago

aldycool commented 2 years ago

Hi @89luca89 ,

I'm still trying to adapt this to run in Ubuntu 20.04, now on the k3s-deploy role, I'm getting this error:

"Failed to run kubelet" err="failed to run Kubelet: failed to create kubelet: open /dev/kmsg: permission denied"

I've searched this error, and everything points to either non-root user, or LXD, but I know none of these is actually used in the configuration.

Do you know something that may have caused this? Thanks.

Hi @aldycool from a first search online it seems a problem between k8s and LXD, here is a discussion:

Hi @89luca89 ,

Yes you're right, it is about the Ubuntu's LXD which is carried by snap in a fresh Ubuntu 20.04 installation, and it is installed by default (listed in the snap list command). I'll try remove it, but most likely this is what causing the error. Thanks again for your help!
