Public bug reported: I don't think this matches the ones that search turned up.
I was upgrading a Linode VM from 14.04 to 16.04 (do-release-upgrade), and after seeming to upgrade everything(?), it spat this out at the end: ================================================================================== Errors were encountered while processing: pptpd Error in function: A fatal error occurred Please report this as a bug and include the files /var/log/dist-upgrade/main.log and /var/log/dist-upgrade/apt.log in your report. The upgrade has aborted. Your original sources.list was saved in /etc/apt/sources.list.distUpgrade. SystemError: E:Sub-process /usr/bin/dpkg returned an error code (1) Could not install the upgrades The upgrade has aborted. Your system could be in an unusable state. A recovery will run now (dpkg --configure -a). Please report this bug in a browser at http://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+filebug and attach the files in /var/log/dist-upgrade/ to the bug report. installArchives() failed Setting up pptpd (1.4.0-7ubuntu0.1) ...

I will attempt to see what happens after reboot. (Worst case, I will restore from the snapshot I took just before the upgrade attempt) ** Affects: ubuntu-release-upgrader (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1615916 Title: Ubuntu upgrade failed 14.04 -> 16.04 (pptpd) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/1615916/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
