Here is a node installation guide Namada v0.23.1
[Update version 0.23.2]
cd $HOME
sudo apt update && sudo apt upgrade -y
sed -i '/NAMADA_TAG/d' "$HOME/.bash_profile"
NEWTAG=v0.23.2
echo "export NAMADA_TAG=$NEWTAG" >> ~/.bash_profile
source ~/.bash_profile
cd $HOME/namada
git reset --hard HEAD
git fetch && git checkout $NEWTAG
make build-release
#cargo fix --lib -p namada_apps
systemctl stop namadad
