Title:
  "netplan apply" does not set file mode, umask 077 causes systemd-
  networkd to be unable to start

Status in netplan.io package in Ubuntu:
  In Progress
Status in nplan package in Ubuntu:
  Confirmed

Bug description:
  If you set your UMASK in /etc/login.defs to 077 then after running "netplan apply" systemd-networkd won't be able to read its configuration files and start:
  systemd-networkd[2826]: Could not load configuration files: Permission denied

  Annoyingly to report such a thing as bug you need a proper network
  connection with working DNS before you submit in ubuntu-bug or it will
  just quit and lose the report. A workaround seems to be to run
  "ubuntu-bug nplan" then in another terminal run "umask 022" then
  "netplan apply" before submitting.
