Comment 3 for bug 966451

Trying to update a ppc ubuntu install is nearly impossible. Update Manager didn't have the Software Sources, downloading the 12.04 iso and burning it to a CD half a day ago didn't work; I learned later because I chose update while upgrading but there are no sources for 12.04 ppc in the cdimages multiversii or anywhere else on this planet. I managed to start the process by saying "no" to updating while upgrading: the most important step since the install will 100% for sure fail due to the absence of sources. By then I'd copied the iso to a new directory as outlined in a Upgrading wiki so the it could emulate an alternate CD. "8 hours remaining' the progress bar estimated once the upgrade had 'downloaded' the info from the iso. 4 hours later I'm told that xscreensaver and xlockmore may lock users out if I don't "arrange for these programs to be restarted or stopped before continuing this upgrade"?? Neither can be started or stopped in a terminal. I have no idea what xlockmore is. In the middle of an upgrade can I delete them? How would I find them? The upgrade has already taken over 15 hours ( I made the mistake of doing something else after 8 hours at it, thinking it was finally going to upgrade, no it just stopped and waited for my full attention so I could answer some stupid question like do I want lxdm default which later is deleted anyway). After a full day of upgrading I may be locked out anyway? Bug is a good word for this upgrade experience and I have no idea whether disabling xscreensaver satisfies the either/or restart or stop instructions so why bother googling to find out what xlockmore has to do with anything.
