Por o wiki do golang github -
If you're using Ubuntu 16.04 LTS, 18.04 LTS or 18.10, then you can use the longsleep/golang-backports PPA and install Go 1.11. Note that golang-go installs latest Go as default Go. If you do not want that, install golang-1.11 instead and use the binaries from /usr/lib/go-1.11/bin.
sudo add-apt-repository ppa:longsleep/golang-backports
sudo apt-get update
sudo apt-get install golang-go
