Trying to narrow down this case. Installing plucky, removing kdump-tools, doing a release-upgrade (without an issue), then being on questing (with no kdump-tools installed). Using this as test bed for: Installing the plucky kdump-tools version on questing (which worked fine), and then updating it to the questing kdump-tools version, which worked also fine. This let's me assume that coreutils is probably not the issue here.
I also thought that this issue might have been introduced with a recent s390x-related change in kdump-tools 1:1.10.7ubuntu1 (https://launchpad.net/ubuntu/+source/kdump-tools/1:1.10.7ubuntu1) after a merge from Debian, but again the above let's me think that the kdump- tools package itself seems to be okay. So all this lets me think now that it is probably more caused by the ubuntu-release-upgrader rather than the kdump-tools package itself (whereas kdump-tools of course should never crash). ** Also affects: ubuntu-release-upgrader (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to kdump-tools in Ubuntu.
