@fantonifabio: as a normal Ubuntu user, unaware of the official Ubuntu dev/test/release lifecycle but eager to have this bothering bug finally fixed, I have tested your fix at the best of my understanding as follows:
1. sudo add-apt-repository ppa:fantonifabio/ubuntu-fixes 2. sudo apt update 3. clicked on the "Back In Time" desktop launcher (non-root user): success -> Back In Time UI displayed 4. clicked on the "Back In Time (root) desktop launcher (root user): failure -> nothing visible happens 5. Issued command: sudo backintime-qt from the command shell: success -> Back In Time UI displayed, configured with my existing profile. I think the difference is the scripts invoked by the two desktop launchers: /usr/bib/backintime-qt and /usr/bin/backintime-qt_polkit respectively. What is wrong with the latter, it's hard for me to tell. But I hope this can help your debugging. However, I agree with @ventusfahrer's assumption that backintime-qt 1.2.1-3 was never tested for Ubuntu 22.04: if it had, the incompatibility with Python 3.10 would have been discovered immediately. So, having to test anyway, why not test Backintime 1.3.2 right away? I think that, at this point, upgrading Backintime to 1.3.2 could not lead to a worse situation than we are facing now. So I urge Canonical team to go for it. Overall, as an Ubuntu's fan since 2010, I feel depply disappointed in seeing Ubuntu 22.04, the latest LTS release, coming out with untested packages and undiscovered bugs, just to honor the announced deployment deadline: a delayed release of a fully-tested system is preferrable, in my opinion, to a timely release of a buggy one. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1970090 Title: Backintime not launching because of python error To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/backintime/+bug/1970090/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
