I performed a couple more upgrade tests and this really is quite a corner issue. It seems that the OS being upgraded must be on drive sda and grub must be installed in the pbr rather than the mbr for the user to even be confronted with the dialog window asking where to install grub. Since only the mbr's of the existing drives appear as choices, if the user selects nothing it triggers this bug which also results in not all old kernels being cleaned up, but it can be resolved post-upgrade by running "sudo update-grub" followed by "apt-get -f install".
So I suppose it could be argued that whenever the criteria is met for the upgrade process to display the grub-install dialog that the pbr of the appropriate partition(s) should be displayed as well as just mbrs. Regardless I think it's a low priority bug. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1351414 Title: package grub-pc 2.02~beta2-9ubuntu1 failed to install/upgrade: ErrorMessage: subprocess installed post-installation script returned error exit status 1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1351414/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
