Hi,

I've just attempted to update the firmware on my Raspberry Pi4
I installed Beowulf Lite 64 bit for the Pi4 back in May this year and have
just attempted to update the firmware ...

# apt-get install raspi-firmware

Anybody any ideas how I get the latest firmware, or where/who else
is better to ask?
