Upgrade from 2.4.6 -> 2.5.1

I upgraded my Rancher installation (standalone docker container) and there are two messages in the Rancher log popping up every second:

time="2020-10-09T18:00:31.837530296Z" level=info msg="Waiting for containerd startup: rpc error: code = Unimplemented desc = unknown service runtime.v1alpha2.RuntimeService"
time="2020-10-09T18:00:32.063809685Z" level=info msg="Waiting for master node local-node startup: nodes \"local-node\" not found"

Clicking on ‘local’ cluster opens page with ‘Graph information from Cluster currently not available’ and it has 0 nodes.
Other cluster (the one that was managed by Rancher before) seems to be OK and functional.

UPDATE: after VM restart I’m not seeing these 2 log messages, but there are these logs now:

[storage/driver] 2020/10/09 18:36:04 query: failed to query with labels: the server could not find the requested resource (get configmaps)

 requested resource (get configmaps)
E1009 18:36:20.846641      25 scheduler.go:638] error selecting node for pod: no nodes available to schedule pods

Local cluster state seems to be stuck in ‘Upgrading’.

Is there any way to bring it back to normal or is it normal?
