Golang/Install

Ubuntu Install

Ubuntu LTS 16.04

Download from https://golang.org/dl/ and extract it into <coede>/usr/local, creating a Go tree in /usr/local/go

sudo tar -C /usr/local -xzvf go$VERSION.$OS-$ARCH.tar.gz

Add /usr/local/go/bin to the PATH environment variable. You can do this by adding this line to your /etc/profile (for a system-wide installation) or $HOME/.profile:

export PATH=$PATH:/usr/local/go/bin

Multiple versions

You can have multiple versions fo Golang installed in your system. The way to manage the current version in use is to use update-alternatives

Before

  Selection    Path                  Priority   Status
------------------------------------------------------------
  0            /usr/bin/golang-go     10        auto mode
  1            /usr/bin/gccgo-go      5         manual mode
  2            /usr/bin/golang-go     10        manual mode

Installed manually unzipped GoLang into /usr/local/go but was not added to alternatives. Use command below to add it on:

sudo update-alternatives --install "/usr/bin/go" "go" "/usr/local/go/bin/go" 2

After

  Selection    Path                  Priority   Status
------------------------------------------------------------
* 0            /usr/bin/golang-go     10        auto mode
  1            /usr/bin/gccgo-go      5         manual mode
  2            /usr/bin/golang-go     10        manual mode
  3            /usr/local/go/bin/go   2         manual mode

Then run command to change go binary available in your shell

sudo update-alternatives --config go  #then select 3

When you run

$ go version #the version of go will be the one from /usr/local/go location.
