I have a similar problem with intrepid 64 and hardy 64. Before the installation, the computer had 2 disks of 500 GB, and the installation of hardy 64 working successfully.
We have replaced the primary disk with a 1 TB disk and the installation quit with ubiquity error report. I used "ubiquity --no-migration-assistant" and the installation not working. For solving this problem, we have disconnected the secondary 500 GB hard disk and only let the 1 TB disk. With the 1 TB disk only, the installation of Intrepid 64 or Hardy 64 working successfully. -- almost at the end of installation https://bugs.launchpad.net/bugs/234835 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
