I'm marking this bug as a duplicate of #1971650 . The general goal is to
move to needrestart rather than continue using the current postinst
script.

Title:
  Restarting services puts puppet into restart-loop

Status in openssl package in Ubuntu:
  New

Bug description:
  Puppet is a configuration and software management system that can be
  used e.g. for installing and upgrading debian packages, modifying
  configuration files, etc. Puppet will call apt-get/dpkg when needed to
  handle packages.

  When libssl1.1 is installed/upgraded and the installation process is
  controlled by Puppet, the automatic re-start of ssl-dependant services
  Puts puppet into a re-start loop:

     1. libssl1.1 's postinstall script re-starts puppet via systemd (systemctl restart puppet.service)
     2. systemd will terminate all processes associated with the Puppet service
     3. dpkg is among these processes since it's called by Puppet and inherits its cgroup-memberships.
     4. libssl1.1 's postinstall script will never succeed since it's killed by systemd
     5. puppet re-starts
     6. puppet runs "dpkg --configura -a" 
     7. libssl1.1 is unconfigured, the postinst script is run
     8. goto 1.

  Puppet should be removed from hardcoded list of services to be re-
  started in libssl1.1's postinst script. A patch to do so is attached.
