Just in case it helps - I had the 141 error too trying to install kubuntu 10.10 daily build 20 Sep into a virtualbox VM. I think the Disk setup has not got permission to create partitions. Lack of "sudo"?
Boot the live CD and open a terminal sudo partman and then go through, auto creating partitions and filesystems (but you might want to be a bit selective). The run the install, and it works. -- ubi-partman failed with exit code 141 https://bugs.launchpad.net/bugs/617729 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
