I can also confirm that this is indeed a problem with the final 11-04 AMD64-image.
I posted details here at first: https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/730209/comments/38 IMHO this should be a critical bug. As the alternate cd fails after the partitioning step when run from usb (probaly because it uses on of the partitions as a temp dir) and the netinstall image takes a good 90 minutes to complete an install (not to mention it is very beginner- unfriendly), the install functionality should really just work off of the live cd. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/757720 Title: ubi-partman crashes with exit code 141 during live install -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
