This affects Ubuntu 11.04 Beta1,Beta2 and the final release. (all 64 bit versions). Did not face this problem in earlier versions of Ubuntu.
I have the exact same problem here. Did not select anything to migrate, but migration assistant still runs anyway. Like Greg, I have multiple installations (Maverick 64 bit, Debian 32 bit, Hardy 32 bit, GRUB2 under Maverick's control). Migration assistant displays an error dialog saying that it could not unmount some partition. Used mount command and found that many partitions were mounted under /target and one of them (/dev/sda8) was mounted under /target/home. Could not manually unmount any of them including /dev/sda8. If I choose 'Continue', the same dialog is shown again. 'Go back' just skips the remaining installation steps and says that the installation is over (even though it's not). IMO this should be atleast Medium if not High since even installation is not possible. ** Also affects: migration-assistant (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/689816 Title: ubiquity migration assistant did not unmount other Linux volumes -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
