Backup Error dnsmasq to SMB-Share

[mrmarkuz (Markus Neuberger)]

Here is the working update command for node 1, if there are more nodes, just add them to the command:

NS8 join cluster with core version mismatch

To update the core of the new node to version 3.21.0: api-cli run update-core --data '{"core_url":"ghcr.io/nethserver/core:3.21.0","nodes":[1]}' After the update it should be possible to join the new node to the leader.
