I ran into the same problem when trying to install Edgy together on my Feisty installation. Resizing the ext3 partition (created by Feisty) during Edgy install failed with some non-verbose error like "unable to resize partition". I've opened another terminal (Alt+F2) and tried parted. It gave me the following error message: "Error: File system has an incompatible feature enabled".
According to "parted --version", Edgy's using v1.7.1. -- This ext2 filesystem has a rather strange layout (newer ext2/ext3) https://launchpad.net/bugs/59620 -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
