Research direction

Start with the mint-upgrade entry point and reproduce the described apt-get upgrade/dist-upgrade path from Linux Mint 21.3 to 22, paying attention to the grub-efi-amd64-signed, grub-efi-amd64-bin, and base-files packages named in the report. Done means the upgrade completes with the expected Mint 22 packages installed and the system remains bootable; the payload names no source files or tests.

Written by the indexing model from the issue text.

Description

Multiple attempts to use mint-upgrade to upgrade from Linux Mint (Cinnamon) 21.3 to 22 failed with the system unbootable.

Use of boot-repair from a Linux Mint Live environment did not fix the problem.

After restoring to a working LM 21.3 via Timeshift,

  apt-get upgrade
  apt-get dist-upgrade 

also produced an unbootable system, but revealed that grub-efi-amd64-signed and grub-efi-amd64-bin had not been installed.

In the attempted upgrade using apt-get upgrade and dist-upgrade, those packages had been held back due to phased updates.

Forcing installation of grub-efi-amd64-signed (bringing grub-efi-amd64-bin in as a dependency) resulted in a bootable system.

Some references to LM 21.3 persisted because the LM 22 version of the base-files package had not been installed; LM's versioning causes the LM22 package to be considered a "downgrade". Installing base-files, specifying the LM 22 version of the package:

  apt-get install base-files=13ubuntu10mint22.0.0+wilma

fixed that. I have no idea what else, if anything, was not successfully upgraded.
