Can confirm this breaks unattended upgrades of 16.04 devices with hwe installed:
# dpkg-reconfigure linux-image-4.15.0-20-generic /usr/sbin/dpkg-reconfigure: linux-image-4.15.0-20-generic is broken or not fully installed # dpkg-reconfigure linux-image-4.15.0-20-generic --force /var/lib/dpkg/info/linux-image-4.15.0-20-generic.postinst: 50: /var/lib/dpkg/info/linux-image-4.15.0-20-generic.postinst: linux-update-symlinks: not found However I don't know how it can happen but the grub is modified, and it won't ever reboot. root@player-3fd4:~# cat /boot/grub/grub.cfg | grep 4.15.0-20-generic | wc -l 10 We have lost hundreds of devices today after reboot with no seemingly possible remote intervention. This is going to be a nightmare for a lot of people... -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1770053 Title: package linux-image-4.15.0-20-generic 4.15.0-20.21~16.04.1 failed to install/upgrade: subprocess installed post-installation script returned error exit status 127 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-signed-hwe-edge/+bug/1770053/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
