In Ubuntu 18.04 LTS, the default Go lang version is 1.10. For compatibility reason, the Ubuntu LTS will usually keep the major release version numbers for packages. However, many applications, such as Hyperledger Fabric 2.0, require a newer version of Go. In this post, let’s take a look at how to install a system level Go of a higher version. Here, we use version 1.13.9 as an example.
An automatic installation script If you prefer to use a script to do this for you, you may run install-go.sh to replace step 2-4.
Step 1. remove all go related packages in your system

It’s a good idea to remove all old go related packages in your system to avoid conflicts.
Step 2. download the go lang release package
You can find the link from Go lang download page.
You will see output as follows.

Step 3. unpack the package to a local path
Unpack the downloaded package and move it to
/usr/local/go-1.13 as the go root path. Here, we use a
1.13 suffix in the directory name so that later we may install multiple version of Go in the system if it is needed. Note, if the directory
/usr/local/go-1.13 already exists, please remove it first.
$ tar xf go1.13.9.linux-amd64.tar.gz $ sudo mv go /usr/local/go-1.13
Step 4. add script to set up environment
Add a file
/etc/profile.d/Z99-go-1.13.sh which contains following content.
export GOROOT=/usr/local/go-1.13 export PATH=$GOROOT/bin:$PATH
It sets the
PATH environment variables for the Go we installed.
Now, log out and log in again so that new settings take effect for your login session.
Step 5. verify the new Go installation
Run a list of commands to verify whether Go works and the one invoked is the required version as follows.
Verify the command
go runs the correct executable binary file.
$ which go /usr/local/go-1.13/bin/go
Verify the version is indeed the one we installed.
$ go version go version go1.13.9 linux/amd64
GOROOT environment variable is correct.
$ go env ... GOROOT="/usr/local/go-1.13" ...
Now, everything good. Enjoy!
