I am now confused: - my 64-bit server upgraded from a CD burnt from the 20110915 daily 64-bit server ISO, with no problems - upgrade of a 64-bit VM which has no additional software succeeds using the 64-bit alternate ISO 20110920.5 - attempts to upgrade my main PC, running 64-bit natty, fail with the same error, during step 2 (setting new channels), using a CDRW created from any of: * 20110915 64-bit alternate ISO * 20110915 64-bit server ISO 20110920.5 64-bit alternate ISO
In addition, do-release-upgrade can't find a development release, so I can't even use that to upgrade: tim@zaphod:~$ sudo do-release-upgrade -d [sudo] password for tim: Checking for a new ubuntu release No new release found tim@zaphod:~$ The attempts to upgrade my main system DID fetch packages files from an acceptable repository even if I chose "NO" at the "Fetch latest updates from the network" question. It appears that the question only affects packages that are available from the CD - the packages fetched were from universe or multiverse or from the partner repository http://archive.canonical.com/ubuntu. If that is the case, then the message is misleading. There is a (or at least a potential) secondary bug, because the upgrade process didn't recognise ucmirror.canterbury.ac.nz as a valid mirror, although natty synaptic offers that as a choice. I suspect that the upgrader doesn't recognise anything other than "*.archive.ubuntu.com" as a valid mirror. I discovered this when I switched mirror after discovering that the Citylink mirror that is considered official (nz.archive.ubuntu.com => ubuntu.citylink.co.nz) was not up-to-date, and tried to do the release update after selecting ucmirror.canterbury.ac.nz. With ucmirror.canterbury.ac.nz, I got 'no valid mirrors found' -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/848659 Title: Upgrade from natty fails with 64-bit oneiric beta cd To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/update-manager/+bug/848659/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
