How to install the current version of Go in Ubuntu Precise

Running sudo apt-get install golang-stable, I get Go version go1.0.3. Is there any way to install go1.1.1?

[Updated (previous answer no longer applied)]

For fetching the latest version:

sudo add-apt-repository ppa:longsleep/golang-backports
sudo apt update
sudo apt install golang-go
