Public bug reported:
Uncertain on the mechanics, so not sure if grub is the right package.
This has happened to me on multiple systems, including a physical system
running on a Core i5 and on a VMware virtual machine. Large amounts of
searching on Google nets no answer for this, nor bug reports filed;
meanwhile attempting to file a bug report is nigh-impossible because
Launchpad sends you to a page which actively-discourages filing bug
reports through Launchpad by putting the link to the bug filing page 2/3
of the way down, but that is an issue for a separate bug.
grub-install will fail in the following way:
Setting up grub-efi-amd64-signed (1.66.6+2.02~beta2-36ubuntu3.6) ...

grub-install: error: cannot open `/boot/grub/x86_64-efi/btrfs.mod': No space

Grub won't boot because these aren't properly installed. I can install them
with cp:
$ sudo cp /usr/lib/grub/x86_64-efi/{btrfs,terminfo}.mod /boot/grub/x86_64-efi/
$ ls -l /boot/grub/x86_64-efi/terminfo.mod

$ ls -l /boot/grub/x86_64-efi/btrfs.mod
-rw-r--r-- 1 root root 19688 Jan 5 09:53 /boot/grub/x86_64-efi/btrfs.mod
Re-running the configure nets this:
Setting up shim-signed (1.19~16.04.1+0.8-0ubuntu2) ...
Installing for x86_64-efi platform.
grub-install: error: cannot open `/boot/grub/x86_64-efi/tga.mod': No space left

dpkg: error processing package shim-signed (--configure):

Errors were encountered while processing:

E: Sub-process /usr/bin/dpkg returned an error code (1)
By repeatedly copying the files by hand and reconfiguring, I can successfully
complete the post-install.

No DKMS packages installed: not changing Secure Boot validation state.
So something is wrong with grub-install such that it fails to copy files
because it imagines the target is out of space, whereas cp can in fact copy the
file.
