Continuing: 1.
So i tried the same with other mirrors from https://wiki.ubuntu.com/Mirrors?highlight=%28mirrors%29 namely: ftp://ftp.belnet.be/pub/mirror/ubuntu.com/ and ftp://sunsite.informatik.rwth-aachen.de/pub/Linux/ubuntu/ubuntu/ both are not recognised (unknown mirror) in the upgrade process, so the wiki page has misleading info 2. from there i tried: https://launchpad.net/ubuntu/+archivemirrors and both have differences.. (not relevant for this bug, but amusing: so i decided i should make this more clear on the wiki page / mirrors, but for some reason is the password for launchpad which is kept by firefox, not the right one; although i am logged in with it on launchpad, unable to change my password in launchpad, still following?:) So i didn't change the wiki..) 3. Some interesting errors: after running the update-manager -d again: 2008-05-15 21:44:43,775 INFO release-upgrader version '0.87.24' started 2008-05-15 21:44:44,164 DEBUG Using 'DistUpgradeViewGtk' view 2008-05-15 21:44:44,261 DEBUG enable dpkg --force-overwrite 2008-05-15 21:44:44,411 DEBUG lsb-release: 'dapper' 2008-05-15 21:44:44,412 DEBUG _pythonSymlinkCheck run 2008-05-15 21:44:45,875 DEBUG checkViewDepends() 2008-05-15 21:44:45,875 DEBUG need backports 2008-05-15 21:44:45,875 DEBUG getRequiredBackports() 2008-05-15 21:44:45,876 DEBUG writing prereuists sources.list at: '/etc/apt/sources.list.d/prerequists-sources.dapper.list' 2008-05-15 21:44:45,957 DEBUG adding '# sources.list fragment for pre-requists (mirror from sources.list + fallback) ' prerequists 2008-05-15 21:44:45,957 DEBUG adding '# this is safe to remove after the upgrade ' prerequists 2008-05-15 21:44:45,957 DEBUG adding 'deb ftp://security.ubuntu.com/ubuntu dapper-backports main/debian-installer deb http://archive.canonical.com/ubuntu dapper-backports main/debian-installer ' prerequists 2008-05-15 21:44:45,957 DEBUG adding 'deb http://archive.ubuntu.com/ubuntu dapper-backports main/debian-installer ' prerequists 2008-05-15 21:44:45,958 DEBUG running doUpdate() (showErrors=False) 2008-05-15 21:45:02,664 ERROR IOError/SystemError in cache.update(): 'Failed to fetch http://archive.canonical.com/ubuntu/dists/dapper-backports/Release Unable to find expected entry main/debian-installer/binary-amd64/Packages in Meta-index file (malformed Release file?)
