Thanks for this additional information. The problem seems to be that you have a bunch of duplicated entries in your /etc/apt/sources.list (and possible /etc/apt/sources.list.d) files. Did you edited those manually or used tools (like the Software Properties window or synaptics repository editor)? It maybe that there is a bug in those tools that makes the duplicates. The bug here is that apt is double queuing those sources.
A simple workaround is to comment out or more most of those sources. Please try to replace your /etc/apt/sources.list file with the one attached and remove anything in /etc/apt/sources.list.d (make a backup of your /etc/apt/sources.list first please). ** Attachment added: "sources.list" http://librarian.launchpad.net/7364070/sources.list -- Edgy > Feisty Alt CD upgrade update-manager fails https://bugs.launchpad.net/bugs/107881 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
