Install Golang 1.20 on Ubuntu 22

Golang 1.20 is required for running Polygon Supernets v1.0.0 upwards.

1. Update system

sudo apt-get update
sudo apt-get -y upgrade

2. Download Go binary

Next we download the Go binary file. It is available here.

mkdir temp
cd temp ( to the folder you created in previous step)
wget https://dl.google.com/go/go1.20.linux-amd64.tar.gz

Extract the downloaded tar and installing into the desired location in the system. Golang's Documentation recommends installing it under /usr/local/go.

sudo tar -xvf go1.20.linux-amd64.tar.gz
sudo mv go /usr/local

3. Environment Setup

We need to set three Go language environment variables -GOROOT, GOPATH, PATH GOROOT - the path where Golang is installed in the mahchine GOPATH - is the location of the working directory

In your .bashrc / .zshrc file add above global variables at the end of the file.

export GOROOT=/usr/local/go
export GOPATH=$HOME/go
export PATH=$GOPATH/bin:$GOROOT/bin:$PATH

4. Renewing the shell sessions

source ~/.profile

As a final check, run the command below.

go version

If Golang is installed correctly you should see the following output:

go version go1.20 linux/amd64
