Title:
  unbound could not read config file after system upgrade to 22.04

Status in unbound package in Ubuntu:
  New

Bug description:
  I ran a test upgrade of my Ubuntu 20.04 Server to 22.04.
  I already noticed while updating that unbound would not start up again. 
  when the update was done the errors I get are:
