CD-based upgrade from Edgy to Feisty fails on bad CD burns

[LagartoFlojo]

Binary package hint: update-manager

Upgrading from Edgy to Feisty using the Alternate CD and the instructions here (http://www.ubuntu.com/getubuntu/upgrading).
First I got the "calculate" error (https://bugs.launchpad.net/ubuntu/+source/update-manager/+bug/107881) when I did not choose to fetch updates from the Internet. When I tried again and did choose to fetch the updates, everything went smoothly until it started the installation of packages. This failed with the gnome-power-management package.

From the log it looks like the CD has a problem. Could you please run the cdrom test (boot from the cd and choose "Check CD") to see if it is ok?

If it turns out to be a bad disk, update-manager should first copy the files to HD and then start the ugprade to avoid that this is discovered during the upgrade.

[LagartoFlojo (lagartoflojo)]

It turned out that the disk was fine (I booted the computer with it in the CD-ROM drive and did an integrity check).
When I first got the error, I found the file with problems, opened it with file-roller and extracted its contents, and I had no problem with that.
I ended up installing Feisty over Edgy, instead of upgrading.

I concur with Michael that it looks like a hardware problem: either a temporary problem with the CD, or possibly with the hard disk. I disagree with Michael that it makes sense to copy files to the hard disk first: that slows down the upgrade, and introduces problems related to available disk space.

Other people don't seem to have had this problem, and it happened a long time ago. Perhaps it would be appropriate to close the bug report, on the assumption that it was a hardware fluke?

Thanks Lars for looking into this again. I think your argument is good, if anything this is a dpkg bug (or a fluke). I think closing the bug is appropriate at this point (edgy is no longer supported).
