Running Cardano relays and block nodes is a fun project, but upgrading nodes can be a bit of a pain. I compiled some simple steps I used to upgrade from Cardano node 1.26.1 to 1.26.2.

Update/upgrade and install cabal requirements

sudo apt update -y
sudo apt upgrade -y

sudo apt install build-essential curl libffi-dev libffi7 libgmp-dev libgmp10 libncurses-dev libncurses5 libtinfo5 -y
