Comment 16 for bug 1991812

Kinetic verification

a) Specific test for this bug
Reproducing the failure without the syslog user:

ubuntu@k-frr-packaging-regression:~$ id syslog
id: ‘syslog’: no such user

ubuntu@k-frr-packaging-regression:~$ sudo apt install frr -y
(...)
Adding system user `frr' (UID 103) ...
Adding new user `frr' (UID 103) with group `frr' ...
Not creating home directory `/nonexistent'.
chown: invalid user: ‘syslog:adm’
dpkg: error processing package frr (--configure):
 installed frr package post-installation script subprocess returned error exit status 1
(...)

ubuntu@k-frr-packaging-regression:~$ apt-cache policy frr
frr:
  Installed: 8.1-1ubuntu3
  Candidate: 8.1-1ubuntu3
  Version table:

        500 http://br.archive.ubuntu.com/ubuntu kinetic/main amd64 Packages
        100 /var/lib/dpkg/status

Installing the package from proposed works:
ubuntu@k-frr-packaging-regression:~$ sudo apt install frr
(...)

ubuntu@k-frr-packaging-regression:~$ apt-cache policy frr
frr:

  Candidate: 8.1-1ubuntu3.1
  Version table:

     8.1-1ubuntu3 500
        500 http://br.archive.ubuntu.com/ubuntu kinetic/main amd64 Packages

And a fresh install of the proposed package in the same scenario works right away:

ubuntu@k-frr-packaging-regression:~$ apt-cache policy frr
frr:
  Installed: (none)
