@Matthew - See my change to the description for a workaround for upgrading from Quantal to Raring. Having a PPA enabled will not necessarily prevent you from upgrading to Raring, however they will be disabled during and after the upgrade process.
** Description changed: + = WORKAROUND = + + For distribution ugprades one can use 'do-release-upgrade -d' instead of + 'update-manager -d' to avoid this bug on Quantal. + First bug report so any advice would be appreciated. Installed 12.10 with no worries and installed a bit of software and added the redshift repo (https://launchpad.net/~jonls/+archive/redshift- ppa). When i next tried to update my system with software updater (1:0.172) stopped with the error "Failed to download repository information" - and + and "W:Failed to fetch http://ppa.launchpad.net/jonls/redshift-ppa/ubuntu/dists/quantal/main/source/Sources 404 Not Found , W:Failed to fetch http://ppa.launchpad.net/jonls/redshift-ppa/ubuntu/dists/quantal/main/binary-amd64/Packages 404 Not Found , W:Failed to fetch http://ppa.launchpad.net/jonls/redshift-ppa/ubuntu/dists/quantal/main/binary-i386/Packages 404 Not Found - , E:Some index files failed to download. They have been ignored, or old ones used instead.". + , E:Some index files failed to download. They have been ignored, or old ones used instead.". I fixed this by unchecking the redshift PPA in software sources. I am sure update-manager used to continue updating all other packages while leaving the one that the source could not be found for, rather than not updating anything in the system including security because of one insignificant package? - ProblemType: Bug - DistroRelease: Ubuntu 12.10 + ProblemType: BugDistroRelease: Ubuntu 12.10 Package: update-manager 1:0.170 ProcVersionSignature: Ubuntu 3.5.0-13.14-generic 3.5.3 Uname: Linux 3.5.0-13-generic x86_64 ApportVersion: 2.5.1-0ubuntu4 Architecture: amd64 Date: Tue Sep 11 18:11:17 2012 GsettingsChanges: - b'com.ubuntu.update-manager' b'first-run' b'false' - b'com.ubuntu.update-manager' b'launch-time' b'1347357820' - b'com.ubuntu.update-manager' b'show-details' b'true' - b'com.ubuntu.update-manager' b'window-height' b'901' - b'com.ubuntu.update-manager' b'window-width' b'569' + b'com.ubuntu.update-manager' b'first-run' b'false' + b'com.ubuntu.update-manager' b'launch-time' b'1347357820' + b'com.ubuntu.update-manager' b'show-details' b'true' + b'com.ubuntu.update-manager' b'window-height' b'901' + b'com.ubuntu.update-manager' b'window-width' b'569' InstallationMedia: Ubuntu 12.10 "Quantal Quetzal" - Alpha amd64 (20120903.4) PackageArchitecture: all ProcEnviron: - LANGUAGE=en_AU:en - TERM=xterm - PATH=(custom, no user) - LANG=en_AU.UTF-8 - SHELL=/bin/bash - SourcePackage: update-manager + LANGUAGE=en_AU:en + TERM=xterm + PATH=(custom, no user) + LANG=en_AU.UTF-8 + SHELL=/bin/bashSourcePackage: update-manager UpgradeStatus: No upgrade log present (probably fresh install) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1049046 Title: Software updater stops complete update if only one source cannot be found To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/update-manager/+bug/1049046/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
