Go is a free and open source programming lanuage. This tutorial shows you how to install Go language, compiler, and toolset on Debian or Ubuntu Linux.
From the article page:
If you’re running a recent release of Debian GNU/Linux you’ll find the golang-environment is packaged and available for installation via apt-get as you’d expect. However the go-environment is changing pretty regularly, and these changes are worth following for increased compilation speed, GC-improvements, and similar improvements. With that in mind I find the preferred approach to working with golang is to install binary releases, outside the packaging system, beneath /opt/go.
