In the particular case of bug 2061126, the user did not have mantic- updates enabled, which meant they had out-of-date distro-info-data. This explains how we get None.
It would still be good to have a fallback for this case, but I don't think this is high priority anymore. ** Changed in: ubuntu-release-upgrader (Ubuntu) Importance: High => Low ** Changed in: ubuntu-release-upgrader (Ubuntu) Status: New => Triaged -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2061148 Title: upgrading window shows %s instead of version number To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/2061148/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
