[Bug 2039981] Re: package shim-signed 1.54+15.7-0ubuntu1 failed to install/upgrade: dependency problems - leaving triggers unprocessed

[Steve Langasek]

The error in your log is: 
Setting up grub-efi-amd64-signed (1.193.2+2.06-2ubuntu17.2) ...
$MFTMirr does not match $MFT (record 3).
Failed to mount '/dev/sdb1': Input/output error
NTFS is either inconsistent, or there is a hardware fault, or it's a
SoftRAID/FakeRAID hardware. In the first case run chkdsk /f on Windows
then reboot into Windows twice. The usage of the /f parameter is very
important! If the device is a SoftRAID/FakeRAID then first activate
it and mount a different device under the /dev/mapper/ directory, (e.g.
/dev/mapper/nvidia_eahaabcc1). Please see the 'dmraid' documentation
for more details.

It appears that /dev/sdb1 is failing to mount because it's an NTFS
filesystem that was not cleanly unmounted.

But the "not cleanly unmounted" is not really relevant here, because the
partitions grub is supposed to be mounting at this point are all VFAT
partitions (EFI System Partitions).  So the partition that grub knew was
an ESP at the time Ubuntu was installed, has been replaced with
something that isn't.

So this is not a bug in grub, but a broken system configuration.

You will need to reconfigure the grub package with the command `sudo
dpkg-reconfigure -grub-efi-amd64-signed` to tell grub where your ESP is
now.  (You must have one, because your dmesg output shows that you are
booted in EFI mode.)
