So in this case, the trigger for gconf2 will use modules from the new libpython2.7-minimal which requires libpython2.7-stdlib while libpython2.7-stdlib is not yet unpacked and configured. This is not specific to gconf2 and should be reproducible with other pacakges. ** Tags added: rls-r-incoming ** Summary changed: - upgrade 12.10 -> 13.04 fails with Error in function + upgrade 12.10 -> 13.04 fails : new libpython2.7-minimal used during upgrade while libpython2.7-stdlib is not yet unpacked and configured. ** Package changed: ubuntu-release-upgrader (Ubuntu) => python2.7 (Ubuntu) ** Changed in: python2.7 (Ubuntu) Assignee: (unassigned) => Canonical Foundations Team (canonical-foundations) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1165172 Title: upgrade 12.10 -> 13.04 fails : new libpython2.7-minimal used during upgrade while libpython2.7-stdlib is not yet unpacked and configured.
