I'm seeing the exact same problem, on an up-to-date Ubuntu 16.10 amd64 installation. The only oddity to my configuration is that I'm running the 4.9.6-040906-generic mainline kernel, because the stock Ubuntu kernel has stability issues with the ASUS Zenbook UX501VW. Based upon the original submitter's reported kernel, however, I doubt that's significant to this bug.
For what it's worth, other activities which need to display the authentication dialog (such as unlocking a SSH key) don't appear to be encountering any difficulty. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1660100 Title: Unable to enable or disable repository in Software & Updates To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/software-properties/+bug/1660100/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
