Can't connect to deluge webUI after updating to bullseye

[nnleaf]

Hi,

I recently updated my Debian server to 11(Bullseye) and I can't seem to connect to deluge's webUI after the update.
When checking services (systemctl status deluged), it's active, enabled, and running.

I checked the version here :

Code: Select all

deluged --version
deluged 2.0.3
libtorrent: 1.2.9.0
Python: 3.9.2
OS: Linux 5.10.0-8-amd64

I ran deluge-console and it worked for a bit, then crashed with this error.

I've already tried removing and purging the install, but it that doesn't seem to work either. I did snapshot my VM before upgrading, so going back to Debian 10 for now... If there's anything else needed, let me know.
Thanks!

I did upgrade my VM to Debian 11 unstable and hat no issues with Deluge so far. But as soon as I enable the WebUI plugin and restart Deluge it just wont start anymore. So I suspect it's maybe some cached Python .egg somewhere in the system (Debian 10 used Python 3.8, right?).

After a bit of searching I found this article: https://stackoverflow.com/questions/219 ... -egg-cache
As suggested I created a new directory in my users home and did a "export PYTHON_EGG_CACHE=/home/username/.python-eggs/".
Now Deluge was starting fine with the WebUI plugin enabled, but the plugin itself was not installed.

I looked around, and the default .egg cache directory on Debian apparently is "/home/username/.cache/Python-Eggs"
It had an older .egg in it so I changed that name: "mv browsebutton-0.2.0-py3.7.egg-tmp/ browsebutton-0.2.0-py3.9.egg-tmp/"
Changed the PYTHON_EGG_CACHE variable to the old default: "export PYTHON_EGG_CACHE=/home/username/.cache/Python-Eggs"
Uninstalled and reinstalled Deluge, since the WebUI plugin wasn't installed anymore.
Now it is working with the WebUI.

Hope that helps you figuring out your issue.
