I created a script that wipes my disks of any superblocks and partitions and then recreates the partitions again (using a stored partition table with sfdisk) and the raid devices using mdadm.
If I start the Ubuntu installer, switch to another console and run the script and then proceed to install Ubuntu on the created partitions this bug occurs and the system gets stuck on first boot. If I boot up another Linux install disc, run the script and then start the Ubuntu installer again and install Ubuntu on the created partitions all works fine. So I'm not entirely sure that the bug is in the installer's partitioner. I my case above I didn't touch the partitioner and used the following partition table with sfdisk instead: # partition table of /dev/sda unit: sectors /dev/sda1 : start= 2048, size= 19529728, Id=fd, bootable /dev/sda2 : start= 19531776, size=947265536, Id=fd /dev/sda3 : start=966797312, size= 9975808, Id=fd /dev/sda4 : start= 0, size= 0, Id= 0 -- mount: mounting /dev/md0 on /root/ failed: Invalid argument https://bugs.launchpad.net/bugs/569900 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
