I hava a freshly installed Ubuntu Server 20.04 LTS.
I am using a static IP config (100% sure it is correct, also the YAML is correct)

If you then enter "netplan try" I get this:
--------------------------------------------------------------------------------
Warning: Stopping systemd-networkd.service, but it can still be activated by:
  systemd-networkd.socket

An error occurred: 'NetplanApply' object has no attribute 'state'

Reverting.
Warning: Stopping systemd-networkd.service, but it can still be activated by:
  systemd-networkd.socket
--------------------------------------------------------------------------------

"netplan generate && netplan apply" does work.
I found some other people having these issues too on freshly installed 20.04 and 21.10 and online forums.
