Ok, just tested, i removed python and it's working, so indeed no need for the Windows 7 custom python version.
Just the dll in the Deluge directory. Didn't thought it would be "so easy".

I don't understand what you mean by fix viariation 2 or 3, i looked at the other posts in this thread, and don't see a "fix variation 2 (or 3)" text in any message. Anyway, do you mean i don't need to install python, but just need to install deluge and copy the dll ? I'll try this evening ...

What worked for me was the following: Get a Windows 7 python version on https://github.com/adang1345/PythonWin7 Get the standard windows Deluge installer version on https://dev.deluge-torrent.org/wiki/Download Get the file:https://github.com/nalexandru/api-ms-win-core-path-HACK/releases/download/0.3...

Hello.
Is there a 32bits version by any chance ?

By the command didn't work, i meant it wasn't effective, the command didn't remove the files (when theoricaly it should).
Anyway, i restored deluge, that's what matters.

I had to delete the files in the directory, the add-apt-repository command didn't work.

Finaly !!!
Thanks to your guidances/informations the result of adding deluge ppa, i've been able to go into the /etc/apt/sources.list.d/ directory, delete all qbittorrent related stuff, re-install deluge, now it's working again.

Big thanks, if on my own, i would never had figure out.

The odd things, is that even after adding ppa for deluge, there is no ppa lines in sources.list. Also, when adding ppa for deluge, the result is : Adding deb entry to /etc/apt/sources.list.d/deluge-team-ubuntu-stable-jammy.list Adding disabled deb-src entry to /etc/apt/sources.list.d/deluge-team-ubu...

I think your suspicion is right, because a long time ago there was qbittorent installed. I've removed it already a while ago, but some things probably stayed... If i do apt show libtorrent* there is a LOT of things !!! Unfortunately, i'm probably even less good than you on Ubuntu... :( I don't know ...

I've uncommented the lines in torrentmanager.py.
I've uninstalled all deluge and all packages with "torrent" in the name.
Then re-installed deluge.

Still the same issue "AttributeError: module 'libtorrent' has no attribute 'add_torrent_params_flags_t'"...
