@antonioberben @pgagarinov this should be fixed with the new v0.6.0-alpha.3 version and the new k3s images, current stable version v0.5.1 should also work, but currently does not support the newer k3s images v1.22 or higher.

@matskiv sure, I’ll use k0s for now.

I use docker, Manjaro Linux with kernel 5.10, no special configuration.
