 maas init region+rack --database-uri "postgres://$MAAS_DBUSER:$MAAS_DBPASS@$HOSTNAME/$MAAS_DBNAME"
Error: argument COMMAND: invalid choice: 'init' (choose from 'help', 'nodes', 'node', 'machines', 'machine', 'allocate', 'deploy', 'commission', 'release', 'abort', 'mark-fixed', 'mark-broken', 'power-off', 'power-on', 'ssh', 'devices', 'device', 'controllers', 'controller', 'fabrics', 'fabric', 'vlans', 'vlan', 'subnets', 'subnet', 'spaces', 'space', 'files', 'tags', 'users', 'login', 'logout', 'switch', 'profiles', 'shell')

I have ubuntu 22.04 trying to install maas from scratch allready few times but the same maas init case show’s up.
After it fails I do snap remove maas, apt remove postresql, retry the steps from docu and still the same init case. Any advices ? what’s happening here ?
Cheers
