[Bug 2042866] Re: Warning: Permissions for /etc/netplan/01-use-network-manager.yaml are too open. Netplan configuration should NOT be accessible by others.

I'm fairly sure we can just ditch that file entirely in ubuntu-raspi-
settings now, as ubuntu-desktop-settings should provide an equivalent
under /lib.

Title:
  Warning: Permissions for /etc/netplan/01-use-network-manager.yaml are
  too open. Netplan configuration should NOT be accessible by others.

Status in ubuntu-raspi-settings package in Ubuntu:
  In Progress

Bug description:
  This warning is shown in the system journal (during boot):

  nov 06 17:15:23 fpgrpi generate[840]: Permissions for
  /etc/netplan/01-use-network-manager.yaml are too open. Netplan
  configuration should NOT be accessible by others.

  The file /etc/netplan/01-use-network-manager.yaml came from the
  package ubuntu-raspi-settings-desktop and its post install permissions
  are -rw-r--r-- (group and others readable).

  A simple workaround is to remove the file read permission for group
  and others, as suggested, using this command:

  sudo chmod 600 /etc/netplan/01-use-network-manager.yaml
