I've got the same problem with Gutsy beta: I'm running Windows XP with 3 NTFS partitions and remaining 60GB of unpartitioned space (single hard drive). During installation from the LiveCD I manually partition the free space - one partition for "/" (50GB) and 5GB for swap. The remainder unused. I'm not importing any configurations from my XP installation (the box is unchecked).
Now the problem: at 88% of installation (Importing documents and settings) the same window as described above pop ups. When I click the "go back" button the installation freezes. When I click "Continue" (another installation try) it seems to go on normally. I'll try it once again with the --debug option. -- [gutsy] failed to unmount migrationassistant https://bugs.launchpad.net/bugs/135149 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
