Title:
  sshd not starting because of missing /run/sshd

Status in openssh package in Ubuntu:
  Incomplete
Status in systemd package in Ubuntu:
  New

Bug description:
  I recently upgraded from Ubuntu to 22.04 to 23.04 using do-release-
  upgrade (twice because I upgraded via 22.10). After doing so, sshd
  stopped working. The output of "journalctl -xeu ssh.service" includes
  the line:

  Jun 06 01:51:05 big-bucks sshd[4544]: Missing privilege separation
  directory: /run/sshd

  This fixed the problem: sudo mkdir /run/sshd

  It seems like either the upgrade sequence or the service startup
  sequence should have done this automatically.

  Currently running: ssh/lunar 1:9.0p1-1ubuntu8 all

  
  There was also a problem reported with /run/sshd on bug #1991283, but I guess the fix for that didn't prevent this.
