There was nothing wrong with the install media. It only took me about 10 hours to figure out what was going on. It is complex and involves dmraid and mdadm and boot repair as well as manually setting up the partitions in the installer. Grub refuses to install no matter how you set the partitions in the installer, so you have to run boot repair twice to fix everything.
It eventually ends up running in RAID 1 using dmraid. If you do it right, you can install Ubuntu 14.04 to a software RAID 1, but it is complex. I posted the full instructions on the Ubuntu formus...... http://ubuntuforums.org/showthread.php?t=2229126&p=13047160#post13047160 It would be nice if the "Something Else" choice in the installer offered to help you set up simple software RAID sets using the included dmraid package. Something to add to Wish List perhaps? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1328320 Title: fresh install fails on RAID 1 with failure to update grub To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/1328320/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
