Like many of us waiting for a version of Ubuntu Mate for the Pi 4 I kept looking to see if it was released yet. No. Nothing. However in my search I came across a website that offered promised but when I burned their iso image to the sdc card it failed to boot. The I came across a Youtube video that got me passed the “failed to boot” issue so that I could login. There would still be hurdles to come but I present the procedure here in what I hope will be an almost cut and paste procedure.
