Begin by running the following command to add the golang backports ppa:

sudo add-apt-repository ppa:longsleep/golang-backports

If you get an error such as “add-apt-repository command not found” then you need to run the following command to install add-apt-repository:

sudo apt-get install software-properties-common

Then run the following two commands to update your packages from the ppa and install Go version 1.11:

sudo apt-get update 
sudo apt-get install golang-1.11

Now we need to add the go binary to our path. I like to put his in my `.profile` by typing:

nano ~/.profile

Then scrolling to the bottom and adding the following line

PATH="$PATH:/usr/lib/go-1.11/bin"

Then use the source command to reread your profile.

source ~/.profile

Now type:

go version

And you should see that Go 1.11 is installed.
