Title:
  udev reports error due to NIS usage

Status in systemd:
  Fix Released
Status in systemd package in Ubuntu:
  Incomplete

Bug description:
  I see the following error message when trying to updating udev to 245.4-4ubuntu3.4.
  > systemd-udevd[25721]: do_ypcall: clnt_call: RPC: Unable to send; errno = Operation not permitted

  As it turns out we trigger a security feature of systemd, which
  appears because we use NIS:

  https://github.com/systemd/systemd/commit/695fe4078f0df6564a1be1c4a6a9e8a640d23b67

  The solution is fairly simple:
  $ sudo mkdir /etc/systemd/system/systemd-udevd.service.d/
  $ printf "[Service]\nIPAddressDeny=\n" | sudo tee /etc/systemd/system/systemd-udevd.service.d/override.conf

  And here the full error message occurring during the update:

  Setting up udev (245.4-4ubuntu3.4) ...
  Job for systemd-udevd.service failed because a timeout was exceeded.
  See "systemctl status systemd-udevd.service" and "journalctl -xe" for details.
