Deluge has several issues with libtorrent 2.0. It more or less limps along, but if you check logs it is hiding all kinds of errors. There are some PRs and commits upstream that are relevant, I think: https://github.com/deluge-torrent/deluge/commit/ea609cd3e0193c395c8bea8425559b022eaa26f1 https://github.com/deluge-torrent/deluge/pull/312 That second one still seems to be WIP, so we might not want to merge it yet, but I'm filing an issue so this is recorded somewhere.
