1. How to install Go on Ubuntu
Step 1
We open the terminal and execute the following command to download the latest version of Go:
sudo wget https://golang.org/dl/go1.15.5.linux-amd64.tar.gz
Step 2
Once downloaded, we extract the content to the / usr / local path:
sudo tar -C / usr / local -xzf go1.15.5.linux-amd64.tar.gz
Step 3
Now, we add the go path to the .bashrc / etc / profile file in order for it to be installed throughout the system, we execute:
export PATH = $ PATH: / usr / local / go / bin
Step 4
We apply the changes with the following command:
source ~ / .bashrc
Step 5
We check the version of Go installed with the following command:
go version
Step 6
Alternatively, we can install Go using the Snap package manager with the following command:
sudo snap install --classic --channel = 1.15 / stable go
Step 7
We create a Go file with the following command:
cat> hello-solvetic.go
we enter the following:
package main import "fmt" func main () { fmt.Println ("Hello getFastAnswer!") } 
Step 8
We press Enter to save the changes, now we execute the following to see the result of the above:
go run hello-solvetic.go
2. How to uninstall Go in Ubuntu
Step 1
As soon as you no longer want to use Go in Ubuntu, to uninstall it we are going to first execute the following:
sudo rm -rf / usr / local / go
Step 2
This will delete the extracted file in that path, now we access the binary file:
sudo nano ~ / .bashrc
Step 3
There we must find, if it exists, the $ PATH line and delete its content, if we do so we save the changes with the Ctrl + O keys and exit the editor with the Ctrl + X keys.
We apply the changes:
source ~ / .bashrc
Step 4
We check with "go version" that it is no longer available in Ubuntu:
So we have installed and uninstalled Go in Ubuntu 21.04, 20.10 or 20.04.
