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 140033418155072:error:02001002:system library:fopen:No such file or directory:../crypto/bio/bss_file.c:72:fopen('*.der','rb') 140033418155072:error:2006D080:BIO routines:BIO_new_file:no such file:../crypto/bio/bss_file.c:79: unable to load certificate dpkg: error processing package grub-efi-amd64-signed (--configure): installed grub-efi-amd64-signed package post-installation script subprocess returned error exit status 1 dpkg: dependency problems prevent processing triggers for shim-signed: shim-signed depends on grub-efi-amd64-signed | grub-efi-arm64-signed; however: Package grub-efi-amd64-signed is not configured yet.
