FYI to clarify - these were tested by enabling -proposed as per https://wiki.ubuntu.com/Testing/EnableProposed
# enable proposed so we can install intel-microcode from there # https://wiki.ubuntu.com/Testing/EnableProposed

cat <<EOF | sudo tee /etc/apt/preferences.d/proposed-updates # Configure apt to allow selective installs of packages from proposed Package: * Pin: release a=$(lsb_release -cs)-proposed Pin-Priority: 400 EOF
sudo apt update
Then installed as:
sudo apt install intel-microcode/$(lsb_release -cs)-proposed
And rebooted to test the machine boots correctly.
