[Bug 1787692] Re: package grub-efi-amd64-signed 1.93.4+2.02-2ubuntu8.3 failed to install/upgrade: installed grub-efi-amd64-signed package post-installation script subprocess returned error exit status 1

[Fred Palmer]

I have been booting with the same version of UEFI from Asus since April.
But now either UEFI or Ubuntu is deleting all UEFI entries and creating multiple new UEFI entries from boot device.

I was having issue of UEFI entry not installing at all. 
fred at bionic-z97:~$ sudo grub-install --bootloader-id ubuntu /dev/sda --recheck
Installing for x86_64-efi platform.
Could not prepare Boot variable: No space left on device
grub-install: error: efibootmgr failed to register the boot entry: Input/output error.

I have to boot full install on flash drive and use configfile to boot into working install in sda. 
But something is adding entries from flash drive's ESP. And on reboot added a second BIOS/grub entry (which is not used)

I can see UEFI entries come from flash drive as it has extra bionic & copy folders.
I was then able to add an entry for working install on sda, but reboot erased it.

After boot with efi_not_storage_paranoia
And reset of UEFI to defaults & changing back to my preferred settings
