I could not reproduce the bug. I think the double entries are present in /etc/apt/sources.list
Try opening /etc/apt/sources.list in a text editor and comment out one of the double entries. The problem should be solved afterwards. Please let us know if the problem persists or not. Setting to incomplete for now. ** Changed in: software-properties (Ubuntu) Status: New => Incomplete -- 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 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
