It's because you have a qbittorrent PPA enabled, offering a newer libtorrent than regular so taking precedence, but unfortunately incompatible with deluge(built different, in version 2.0.11 VS 2.0.10). You need remove that ppa, had this issue before with a user here: https://forum.deluge-torrent.org...

Thanks bro for speeding it up with your request at upstream, asking if they need help, appreciated.

No worries buddy, thanks for posting

Well you don't have a functioning libtorrent for deluged apparently - reason here being because your libTorrent is another lib, developed for rtorrent, so need libtorrent-rasterbar2.0t64, python3-libtorrent should pull right one in presumably. Also needs match py3.12. Don't really have experience wi...

As inferred by the good ambipro above, old deluge better worth updating through pip or PPA. Anyway, gettext error fix described here(latter ValueError described there, to be ignored): https://forum.deluge-torrent.org/viewtopic.php?p=236670#p236670 Later xdg-runtime error, is sudo not properly setup ...

Thanks for making ambipro(discussed functionality) Out of our hands as said, part of the gtk widget, sorry.

Thank you my friend for your post

The ppa doesn't yet support 24.04, so need your workaround to be used, however currently a non-issue because 24.04 already has a newer deluge available in own repos than the one in ppa, so the ppa will not be used regardless, as older, and if still wanted, would need be forced. You're not doing anyt...

Awesome thread, thank you for making bud, just wanted say that also in public, better late than never I guess lol. Anyway, nice to have something to point people at, instead of bits and pieces scattered all over, then right here at home. Thanks bro.

Not without changing the code I'm affraid. If remember right, then shift+del ticks that by default(gtk-ui), but not at my computer now to check, and to lazy look up on github honestly.
