Seems this error is user-caused (at least in my case) since I was able to perform a full in-vm release upgrade and solving this bug/error by:
1. Installing these pacakges: sudo apt-get install linux-headers-4.4.0-63-generic --assume-yes sudo apt-get install linux-image-4.4.0-63-generic --assume-yes sudo apt-get install linux-image-extra-4.4.0-63-generic --assume-yes 2. Removing this directory: sudo rm /etc/udev/rules.d/70-persistent-net.rules/ -rf 3. Only then starting do-release-upgrade Removed my bug-count -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1672047 Title: package linux-image-extra-4.4.0-66-generic 4.4.0-66.87~14.04.1 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/linux-lts-xenial/+bug/1672047/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
