It actually seems to be a software-properties bug that wasn't visible before the latest python-apt change.
Since the last python-apt upload, most "templates" now exist twice, once for binary entries, once for source entries. software-properties shouldn't show all of them twice. I have a small patch for this that I'm testing now to make sure we don't get a different behavior from what we had in 10.10. Closing python-apt task as it's not a python-apt issue. software- properties ask python-apt for all existing templates and that's indeed what it receives. ** Changed in: python-apt (Ubuntu) Status: Confirmed => Invalid ** Changed in: software-properties (Ubuntu) Status: Confirmed => Triaged ** Changed in: software-properties (Ubuntu) Importance: Undecided => High ** Also affects: python-apt (Ubuntu Natty) Importance: Undecided Status: Invalid ** Also affects: software-properties (Ubuntu Natty) Importance: High Status: Triaged -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/768469 Title: duplicate entries in the updates section with python-apt-common 0.7.100.3ubuntu5 upgrade -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
