The obvious initial step for this is to enforce the partitioning scheme that we do support (ie. PReP can't be on RAID), and I've been testing a partman-prep update with this.
There's also a big part in grub-installer; I'm preparing a proper fix for this there, pending testing to make sure the firmware understands the way the disks are set up in the case of RAID 1 (because we can't support other RAID levels). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1487365 Title: Ubuntu14.04 .3 RAID installation fails on firestone To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/debian-installer/+bug/1487365/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
