I have encountered the same problem (bzip2 error being thrown when trying to upgrade [from edgy to feisty]) and I believe there may be a cause for this, other than "duplicated entries in sources.list file"
Detailed description of the problem I've encountered can be found here: http://ubuntuforums.org/showthread.php?t=660619 In trying to implement the solution suggested here above, I messed around quite extensively with my original sources.list file (i.e. trying to remove any duplication) but none of my changes produced a different result. So i got a new auto-generated sources.list, and am still encountering the same failure. The new vanilla sources.list is attached. ** Attachment added: "new vanilla sources.list file, that still causes failure" http://launchpadlibrarian.net/11182746/sources.list -- apt throws bzip2/gzip errors for duplicated sources.list entries or duplicated componenes (race condition?) https://bugs.launchpad.net/bugs/102511 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
