This is a warning from the Netplan side, which should not affect functionality.

The permissions (chmod) on /etc/netplan/01-netcfg.yaml should match 0o600 and subiquity might not be using the most restrictive permissions here, yet.

So you can run somethink like this as a workaround:
$ sudo chmod 600 /etc/netplan/01-netcfg.yaml

Let's re-assign to subiquity to double-check that.

Subiquity might not be blamed here, as that system is a long term rollover installation simply ugraded via the sources.list update. Subiquity has never been used on this system.
