Download Go Ubuntu: Everything You Need to Know About Go Programming on Linux


How to Download and Install Go on Ubuntu




Go is an open-source programming language that was created by Google in 2012. It is designed to be simple, fast, and reliable, and it supports concurrency, memory safety, and garbage collection. Go is widely used for developing web applications, cloud services, microservices, artificial intelligence, and robotics.


In this article, you will learn how to download and install the latest version of Go on an Ubuntu 20.04 system. You will also learn how to test your Go installation by creating a simple Hello, World! program in Go. Finally, you will learn how to uninstall Go from your system, if you decide you don't need it anymore.

Prerequisites




Before you start installing Go on Ubuntu, you need to have the following:


  • An Ubuntu 20.04 system configured with a non-root user with sudo privileges and a firewall. You can follow this guide on to set up your system.



  • A terminal window or an SSH connection to your Ubuntu system.



  • A web browser to access the official Go downloads page.



Downloading the Go tarball




The first step is to download the latest version of Go from the official website. At the time of writing this article, the latest stable version of Go is 1.16.7.


To download Go on Ubuntu, follow these steps:


  • Open your web browser and navigate to the .



  • From there, copy the URL for the current binary release's tarball for Linux systems. The file name should end with linux-amd64.tar.gz.



  • Open your terminal window or SSH connection and make sure you are in your home directory by typing:



cd


  • Use curl to download the tarball from the URL you copied, using the -O flag to save it as a file with the same name as the original file, and the -L flag to follow any redirects. Replace the highlighted URL with the one you copied:



curl -OL [13](


  • To verify that the file you downloaded is not corrupted or tampered with, use sha256sum to calculate its checksum and compare it with the one listed on the downloads page:



sha256sum go1.16.7.linux-amd64.tar.gz

Extracting and installing the Go tarball




The next step is to extract the Go files from the tarball and install them to /usr/local, which is the recommended location for Go installations. To do this, you need to use the tar command with sudo privileges.


To extract and install the Go tarball on Ubuntu, follow these steps:


  • Use tar to extract the Go files to /usr/local, using the -C flag to specify the destination directory, and the -xzf flags to extract a gzipped archive. Replace the highlighted file name with the one you downloaded:



sudo tar -C /usr/local -xzf go1.16.7.linux-amd64.tar.gz


  • To make sure that you can run Go commands from any directory, you need to add /usr/local/go/bin to your PATH environment variable. You can do this by appending it to your /.profile file, which is executed when you log in. To do this, use echo with the >> operator to append the following line to your /.profile file:



echo "export PATH=$PATH:/usr/local/go/bin" >> /.profile


  • To apply the changes to your current session, use source to reload your /.profile file:



source /.profile


You have now installed Go on your Ubuntu system and added it to your PATH.


Testing the Go installation




To verify that Go is working properly on your system, you can use go version to check the installed version of Go, and create a simple Hello, World! program in Go.


To test your Go installation on Ubuntu, follow these steps:


  • Use go version to check the installed version of Go. You should see an output like this:



go version go1.16.7 linux/amd64


  • Create a directory for your Go workspace, where you will store your Go code and packages. You can name it anything you like, but a common choice is go. To create it in your home directory, use mkdir:



mkdir /go


  • Create a subdirectory inside your workspace for your Hello, World! program. You can name it anything you like, but a common choice is hello. To create it, use mkdir with the -p flag to create any parent directories as well:



mkdir -p /go/src/hello


  • Create a file named hello.go inside your hello directory. You can use any text editor you like, but a common choice is nano. To create and edit the file, use nano with the full path to the file:



nano /go/src/hello/hello.go


  • In your hello.go file, write the following code, which defines a main package and a main function that prints "Hello, World!" to the standard output:



package main import "fmt" func main() fmt.Println("Hello, World!")


  • Save and close the file by pressing Ctrl+O followed by Enter to save, and then Ctrl+X to exit.



  • Use go run to compile and run your program. You should see the output "Hello, World!" on your terminal:



go run /go/src/hello/hello.go Hello, World!


Congratulations! You have successfully created and executed your first Go program on Ubuntu.


Uninstalling Go (optional)




If you decide that you don't need Go on your system anymore, you can easily uninstall it by removing the Go files and the PATH entry that you added earlier.


To uninstall Go from Ubuntu, follow these steps:


  • Use rm with sudo privileges to remove the /usr/local/go directory and all its contents:



sudo rm -rf /usr/local/go


  • Use nano or your preferred text editor to edit your /.profile file and remove the line that you added to export the PATH variable:



nano /.profile


Delete this line:


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


Save and close the file.


  • To apply the changes to your current session, use source to reload your /.profile file:



source /.profile


You have now uninstalled Go from your Ubuntu system.
