#3437: Deluged Crashes on Startup post python3-libtorrent 1.2.10_git20201018
----------------------------+---------------------
Reporter: guy_montag | Type: bug
Status: new | Priority: minor
Milestone: needs verified | Component: Unknown
Version: 2.0.3 | Keywords:
----------------------------+---------------------
Running on Ubuntu x64 20.04 LTS fully updated.

I'm not an expert and this may be more of an FYI but it seems deluged
2.0.3-2 is not yet compatible with the latest version of
python3-libtorrent.

After upgrading python3-libtorrent to 1.2.10_git20201018 (which comes with
qBittorrent 4.3.0.1 out of their PPA repository), deluged 2.0.3-2 crashes
on startup with error

$ Traceback (most recent call last):
File "/usr/lib/python3/dist-packages/deluge/_libtorrent.py", line 23, in
<module>
import deluge.libtorrent as lt
ModuleNotFoundError: No module named 'deluge.libtorrent'

This happened after installing / upgrading qBittorrent to 4.3.0.1 from
their PPA repository as it seems there is now a dependency from the latest
version of qBittorrent to a later version of python3-libtorrent.

Reverting to qBittorrent 4.2.5 clears the problem - as would reverting to
the much older version in the Ubuntu repository.

So I'm not saying it's a deluge problem - but it would be good if you
could run the latest versions of both programs in parallel.

Is there a way of making different versions of python3-libtorrent
available to the two programs ?
