The problem must have been related to one or more specific packages which were blocking the upgrade. I have removed a number of packages and the problem went away.
The bug I would tag is the complete lack of useful information: why couldn't calculate the upgrade? At which package did it fail? How about a way to trace the execution to narrow down the problem? That is what should be fixed. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1740767 Title: after upgrading to 17.04 and, maybe, running out of disk space, a further upgrade fails To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/1740767/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
