Comment 4 for bug 966451

The upgrade failed at about 95% (by progress bar), screen froze, had to be powered off and was unbootable after rescue resetting to boot with /sda11 as my / partition. I'd backed up my / partition but there were 17 partitions on my HD after a guided install; the old files in / are quite useless with an almost upgraded system. I have yet to upgrade successfully on 2 different dual-boot macs, this was either my 4th or 5th attempt in various 10.4 - 12.10 Ubuntu/Lubuntu upgrades/configurations. I learned not to keep anything 'valuable' on my hard drive but I did have a working system before this upgrade took 18 hours of hacking and guessing and I ended up with nothing. I can't help but think ppc architecture is currently un-upgradable. I have no way of knowing whether this bug was my downfall, xlockmore was not a conscious choice I made to install: in my screensaver preferences I had set my desktop never to lock, I'm assuming the option to lock after screensaver start is what xlockmore is. I had disabled xscreensaver after getting the warnings during upgrade to no avail. 12.04 won't be LTS forever, my approach will be to install 12.04 LTS on the machine I want to have stable and expect to start from scratch when I want a newer kernel.
