Hi tenwit, thanks for your report! You did just right to clean up and complete the installation.
On the error that occurred, what I can find related in your log is: frontend: Fatal IO error 11 (Resource temporarily unavailable) on X server :0. I found various such issues across the past - not frequent but every now and then: - bug 951404 - bug 821630 None came to a perfect conclusion, but it matches the error in your log as well as the symptom "the graphical login having crashed". That took down everything else with it, so the upgrade which you completed later on. You might read through those bugs, there are some hints on lightdm.conf being responsible, but since you are "out of the bug" already that might not matter to you anymore. On the actual issue I don't see openssh related in any way - instead I'll re-file this against Given that this seems to be something like an X server dying checking and attaching those logs might help the Team around lightdm and such as well. ** Package changed: openssh (Ubuntu) => lightdm (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1734212 Title: package openssh-server 1:7.5p1-10 failed to install/upgrade: subprocess installed post-installation script returned error exit status 1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lightdm/+bug/1734212/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
