I had a go at reproducing this. I can't get a successful install from the alpha 2 jaunty installer any more so that didn't help. I also wasn't able to install from any of the kubuntu jaunty ISO images -- they always gave me corrupt file errors. The standard GNOME installer seemed to upgrade fine, and I also tried the mini.iso and installed kubuntu- desktop and that upgraded without problem.
I can't really work out what is going on here. The uuid I see in ash when the boot fails is the one for the root partition. This is the same as the uuid that I see in /boot/grub/grub.cfg after I run update-grub2. What I can't see is where the uuid that it is trying to mount comes from. I tried to disable the grub 2 option for passing the uuid to the kernel, but that made no difference. I suspect that the best thing to do at this point is to write off the installations and re-install both laptops. Hopefully it's a problem caused by jaunty alpha 2 and there won't be too many other people who have problems with this. -- Karmic series kernel won't load encrypted main disk after upgrade from jaunty https://bugs.launchpad.net/bugs/408888 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
