Which version of Ubuntu are you running? The following command will tell you if you're unsure: lsb_release -a
You either need to delete the problematic line, or fix it if you still want to use sabnzbdplus. The line should not be: t/jcfp/ppa/ubuntu natty main # disabled on upgrade to natty but rather: deb http://ppa.launchpad.net/jcfp/ppa/ubuntu natty main # disabled on upgrade to natty You can edit the file with this command: gksu gedit /etc/apt/sources.list.d/jcfp-ppa-maverick.list And when you're finished, run: sudo apt-get update ** Changed in: apt (Ubuntu) Status: Incomplete => New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1005291 Title: Update Manager Bug To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/apt/+bug/1005291/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
