Hi there,

You should provide some more information, like the error message when
you manually launch `/usr/bin/fail2ban-server -vvv -x start`.

Please note that on a default Debian 12.4/bookworm you simply need to
add some lines to `jail.local`, without touching anything else:
```
[DEFAULT]
### <https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1049452#10>
banaction = nftables
banaction_allports = nftables[type=allports]
### <https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=770171#94>
backend = systemd
```

Thx, bye,
Gismo / Luca

Yeah but that shouldn't be needed like in previous distributions fail2ban should just start automatically after install the package

Dear Luca,

I am aware of the fix you've provided, but like Stefaan had said, the
package is supposed to work on a default Bookworm install -- it's how
it works before the systemd switch, and indeed how it works in testing
(Debian 13).

Version 1.0.2-3 ended up in testing, but DID NOT find its way into
stable. We should either seek to move that into stable, or seek to
move the current working version in testing (1.1.0-4) -- with a more
comprehensive systemd patch[0], into stable.
