Yes, do-release-upgrade work again. My ubuntu was installed with virtual machine mode with cd-rom iso and python-apt was not installed before.

The included 'aptsources' Python interface provides an abstraction of the sources.list configuration on the repository and the distro level.

The strange part was that both virtual machine are installed with VM mode (ubuntu 12.10) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/994152 Title: do-release-upgrade says it can not run the upgrade To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/994152/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
