When trying to restore a backup from z9-pbs, the following error message is shown, even though the backup metadata can be loaded successfully:

proxmox-backup-client failed: Error: wrong key - unable to verify signature since manifest's key 21:68:5e:4e:32:b1:b3:cc does not match provided key 21:83:cb:c3:58:21:be:11 (500)

The backups on z9-pbs are a mirror of pbs-local, so the key for that target is used.

Figure out what we need to do on chaosknoten to be able to restore from that storage.

Also make sure we have copies of the keys in the appropriate repo.

It seems a no longer used key was still setup for z9-pbs and therefor broke the restore procedure.
The key from pbs-local has now been copied to the other remote in the config file so restores should work now
