Public bug reported:
Fix this:
On some Thinkpads (up to now, no other manufacturers appear to show
this), db can be reported to be empty even though it's not. It seems to
be a firmware issue, but it's one we can work around.
So, fix this type of failure:
Setting up grub-efi-amd64-signed (1.112+2.02+dfsg1-5ubuntu10) ...
db is empty
Can't open *.der for reading, No such file or directory
