My Pi 4 has got stuck during an upgrade.  I just did 'apt update'
followed by 'apt upgrade' (after 'sudo -i') and it went entirely normally
until:-

    Adding 'diversion of /boot/fixup4x.dat to
/usr/share/rpikernelhack/fixup4x.dat by rpikernelhack'
    Adding 'diversion of /boot/LICENCE.broadcom to
/usr/share/rpikernelhack/LICENCE.broadcom by rpikernelhack'
    Unpacking raspberrypi-bootloader (1.20201201-1) over (1.20201022-1) ...
    Setting up raspberrypi-kernel (1.20201201-1) ...
    Removing 'diversion of /boot/kernel.img to
/usr/share/rpikernelhack/kernel.img by rpikernelhack'

... and that's it, stuck at 52% progress.

The Pi is still running, I can ssh into it from another terminal window and
things seem fairly normal but I'm not sure how to progress/finish the upgrade.

This is an early Pi 4 with only 1Gb memory.
