As you can see, python fails to find libtorrent...
Can you please run python3 -c "import libtorrent; print(libtorrent.version)"?

Thanks for your answer but i've recently reinstalled/upgraded my server OS to Ubuntu 22.04 so I can't run that test.

Anyway:

• I got a solution at ​https://forum.deluge-torrent.org/viewtopic.php?f=7&t=56140
• I've moved my deluge server to a docker container version running on my nas. ​https://hub.docker.com/r/linuxserver/deluge

Confirming this is a REGRESSION bug. deluged was working fine until a recent upgrade.

2022-09-10 08:41:00 upgrade deluged:all 2.0.5-0~202202181912~ubuntu18.04.1 2.1.1-0~202207101304~ubuntu18.04.1

^{after this, deluge was failing to start. Upon inspection we can see the same as reported above.}

-- Unit deluged.service has finished starting up.
-- 
-- The start-up result is RESULT.
