I tried doing another install using the Edgy RC1 nightly build from Oct 17 2006. Using the graphical installer I selected the clean install option (delete existing partitions and create new ext3 and swap partitions) and this time the installation completed successfully.
Edgy beta1 had gotten stuck at "update-grub" under the same conditions. -- SATA HDD not recognized during Breezy Colony 4 install or Dapper Flight 3 https://launchpad.net/bugs/19749 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
