FWIW mine appears to have hung during a hidden (invisible to me) step where it was attempting to set a MOK. I had to first kill the existing dpkg, then edit /usr/sbin/update-secureboot-policy to change #!/bin/sh to #!/bin/bash (I was getting a local variable error), then manually run /usr/bin/perl -w /usr/share/debconf/frontend /usr/sbin/update- secureboot-policy --enroll-key, then reboot, install the key, finish booting, and dpkg --configure -a.
I have no idea if the terminal-gui app that is attempting to ask for a password for the MOK can be surfaced into the apt/dpkg configurating process, but that seems to be the missing link for me. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1776076 Title: package virtualbox-dkms 5.2.10-dfsg-6 failed to install/upgrade: installed virtualbox-dkms package post-installation script subprocess was killed by signal (Killed) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/dkms/+bug/1776076/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
