Comment 15 for bug 148023

Not sure whether this is the same bug.

Environment: 6.10 installation, trying to upgrade to 8.04 (preserving /home, discarding everything else).

I told the installer to format all partitions except /home, thinking it would realize I was trying to do a clean install, not an upgrade. No luck. The "Ready to Install" page had the following error message:

10 migration-assistant/sda9/users doesn't exist: 10 migration-assistant/sda9/10+migration-assistant/sda9/users+doesn't+exist/items doesn't exist

And then after the install "finished" and I was presented with a desktop, it turned out that none of my partitioning instructions had been followed -- the non-/home partitions were mounted on /target, /target/tmp, etc., rather than /, /tmp, etc., and /home was mounted on /mnt/migrationassistant.

I tried following the "Clean Install Upgrade" instructions on https://help.ubuntu.com/community/Installation/UpgradeFromOldVersion , but that didn't work either -- the same thing happened.

FWIW, I have been trying to upgrade my 6.10 installation for over a year -- to 7.04, 7.10, and 8.04. Every time, the installer (ubiquity) has been broken in a different, show-stopping way. And since 6.10 is no longer supported and I can't get updates for it or even load new packages into it, it looks like I'm going to have to go out and buy a new hard drive to do a from-scratch install of 8.04, and then copy the /home partition.
