Yes, i had to fiddle around quite a lot with the package manager to get everything going again and it all works now (the apport information above is from after the upgrade).
That doesn't change the fact that a do-release-upgrade shouldn't just fail in the middle and give up. In my opinion, it should try to upgrade/install as much as possible and then print the couple of missing/broken packages at the end. At the very least, do-release-upgrade shouldn't just die without giving the user at least some basic information of what to try next. ** Changed in: linux (Ubuntu) Status: Incomplete => Confirmed -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1787411 Title: doc-base post-installation script breaks do-release-upgrade from 16.04 to 18.04 Status in linux package in Ubuntu: Confirmed Bug description: On one of my computers, do-release-upgrade from 16.04 LTS to 18.04 LTS broke mid-update.
