I suspect you may have something installed in your test PC that may mask/fix the error.
Please test this: start the PC with the Ubuntu 22.04 LTS CD image. It came with transmission-gtk installed. Just use the option "Try Ubuntu" and repeat the procedure (don't need to install anything, just download the torret with firefox). It will fail... I just tested it and fails...
