Unhandled error in Deferred:

[SSamiK]

So this happend on a fresh install of Linux Mint - I installed Deluge and deluged as per my normal routine.
Set everything up so that it worked.

But there is a couple issues - first of not all torrents shows in the thin client so I had to restart it a few times to get everything to show. Even on the host that runs borth deluge and deluged. Labels would not do "move when completed" as setup.

And all of a sudden deluged just won''t start anymore.
Throws out this bunch of lines:

Any ideas what I can do to fix this? Deluge always have been my favorite client so I really don't want to move to something else.

I have not been able to solve this yet, so please if anyone can chime in I would appreciate it much.
I tried purging Deluge and deluged from my system and reinstalling but no change. I admit not having spent a ton of time trying to figure this out, but that's life.. Just cant find the same amount of time to spend on things like this as in younger years.

For the time being I'm checking out rTorrent and Qbit as possible replacements - both lack a thin client, so they might not fill the deluge-gap but they'll have to do for now.

Any help in this post? viewtopic.php?t=55662
Have you updated the twisted package already?

[ross104]

Upgraded twisted via

Code: Select all

sudo pip3 install --upgrade twisted

Install patch log.py

It helped me, might help you.

[mentor]

Install patch log.py

It helped me, might help you.

How does one install a patch? I'm using the ppa:deluge-team/stable ppa.

Just updating twisted did nothing.

Edit: see this reddit thread.
