Not able to setup a local single node cluster - Failed to setup ssh tunneling

Rancher 1.x
1

Hello all, i’m new of Rancher and i’m following the academy to get practice with it. I’ve created the cluster file using the wizard and specifying just my local ip address, but when i run rke up i got these logs and error:

INFO[0000] Running RKE version: v1.1.0

I already read lots of post about this and i also applied common solutions such as adding the user to the docker group or check ssh configuration but i came up to nothing. About my ssh config i have both private and public keys on default path.

I’m running on Kubuntu 20.04.

Any suggestions would be really useful to let me dig a bit inside this amazing technology
