Extend volume to physical max

#1

hello
installed the ubuntu image on a 64GB sd card. Looks like only a fraction of it is used. Is there anyway to extend the volume to use the entire physical storage?
It’s easy to do something similar on the raspberry Pi 4.

#2

sudo systemctl enable resize-helper

Install Armbian which is far better than “Ubuntu”. This problem is solved automatically.
