grub was "half configured". dpkg was sleeping instead of configuring. Relaunching the installer from a terminal revealed the problem: grub itself was launching a terminal window and asking questions. Under software updater, the window was never displayed.
reboot and then from a terminal window: sudo apt-get clean sudo apt-get update Many things re-installed. During the "update" phase, grub displayed a completely new terminal window which reported that the disk had changed and I needed to identify the new disk (it had not). I fed it one of the choices ( I think /dev/hda) and it was happy, and everything seems to be functional again. I think it was the inability of software updater to permit the terminal window which caused the dpkg to wait for ever. -Chris -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1525469 Title: package unattended-upgrades 0.82.1ubuntu2.4 failed to install/upgrade: subprocess installed post-installation script was killed by signal (Terminated) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/unattended-upgrades/+bug/1525469/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
