Apparantly, even though a fix has been made, there is still no way to install or upgrade to karmic on sparc.

If you attempt upgrade, upstart will fail or crash the system.

If you try to install the system from CD, booting from CD will fail with a "Fast Data Access MMU miss" because not enough memory is allocated to hold both the kernel and the initrd on newer ubuntu releases - Ubuntu Hardy 8.04 was the last release to be able to boot from cd. Lucid and up have solved the memory issue of the cd bootloader, but it does not seem to load the sd driver so you cannot access any block devices even though you have the correct scsi/ide driver loaded.

The only solution left is to install Hardy and then do an LTS upgrade to Lucid - mind you that you might have an issue with apparmor so you should probably remove that package before upgrading.
