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:
sudo update-alternatives --install "/usr/bin/go" "go" "/usr/local/go/bin/go" 2 #adds to the $PATH export PATH=$PATH:/usr/local/go/bin #optional
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
Display best options
sudo update-alternatives --display go go - auto mode link best version is /usr/local/go/bin/go link currently points to /usr/local/go/bin/go link go is /usr/bin/go /usr/local/go/bin/go - priority 2
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
Action: 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 <tt>/usr/local/go</tt> location.
