Bug Description

I upgraded from 21.10 to 22.04 on my workstation just to check out gotchas before the real release comes out, and one I ran into right away that fail2ban would not start.

I totally uninstalled and purged and then re-installed it in case somehow old stuff left was breaking it but fails with this error:

     Loaded: loaded (/lib/systemd/system/fail2ban.service; disabled; vendor preset: enabled)
     Active: failed (Result: exit-code) since Thu 2022-03-10 01:30:13 PST; 7s ago

The bug you say this is a duplicate of is for Impish (where it was formerly working for me) this bug is for Jammy (where it ceased working).
