[Bug 1726679] Re: package shim-signed 1.32+0.9+1474479173.6c180c6-1ubuntu1 failed to install/upgrade: subprocess installed post-installation script returned error exit status 1

[Steve Langasek]

The error in your log is:

Installing for x86_64-efi platform.
grub-install: error: cannot open `/boot/efi/EFI/BOOT/BOOTX64.efi': Is a directory.
dpkg: error processing package shim-signed (--configure):
 subprocess installed post-installation script returned error exit status 1

This indicates that your EFI System Partition has been corrupted.  You
probably need to remove /boot/efi/EFI/BOOT/BOOTX64.efi to let the
upgrade complete successfully.

Reassigning this bug to grub; it's possible there's something we can do
here to make the upgrade more robust.

** Package changed: shim-signed (Ubuntu) => grub2 (Ubuntu)
