Eugene: do you get the exact same error message? Could you please comment the command you run and the error message you see.
Also, since I found the "/usr/lib/python3/dist- packages/aptsources/distro.py" file is part of python3-apt, could you include the output of `apt policy python3-apt` to see which version you are running? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1849835 Title: add-apt-repository does not work in focal To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/software-properties/+bug/1849835/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
