Ubuntu is a popular Linux-based operating system that is free, secure, and easy to use. It has a large community of users and developers, and a rich ecosystem of software and tools. Ubuntu is one of the most compatible operating systems for running Go applications.
In this article, you will learn how to download and install Go 1.17 on your Ubuntu system. You will also learn how to set up the Go environment variables and write a simple \"Hello, world\" program in Go.
Before you start installing Go on Ubuntu, you need to have the following:
An Ubuntu system with version 18.04 or higher
An internet connection
A user account with sudo access
Downloading the Go Binary Archive
The first step is to download the latest Go binary archive from the official website. You can use the wget command to download it from the terminal. The current version of Go is 1.17.7, but you can check the for any updates.
Open a terminal window and run the following command:
This will download a file named go1.17.7.linux-amd64.tar.gz in your current directory. You can verify the file size and checksum using the ls and sha256sum commands:
ls -lh go1.17.7.linux-amd64.tar.gz sha256sum go1.17.7.linux-amd64.tar.gz
The output should look something like this:
-rw-rw-r-- 1 user user 129M Feb 14 22:22 go1.17.7.linux-amd64.tar.gz e0f9c8c4f9b6b0a4f5c5b8e0a6a3f5b6e9e8c3f9f0c0b6a4f5c5b8e0a6a3f5b6 go1.17.7.linux-amd64.tar.gz
Extracting and Installing Go
The next step is to extract the Go binary archive and install it to a desired location on your system. For this tutorial, we will install it under /usr/local directory, which is a common place for installing software that is not managed by the package manager.
To extract and install Go, run the following command:

sudo tar -xvf go1.17.7.linux-amd64.tar.gz -C /usr/local
This will create a directory named go under /usr/local, which contains all the files and directories of the Go installation. You can verify the installation by listing the contents of /usr/local/go:
The output should look something like this:
Setting Up the Go Environment Variables
After installing Go, you need to set up some environment variables to tell your system where to find the Go executable and libraries, and where to store your Go projects. The main environment variables for Go are:
GOROOT: This is the location of the Go installation. By default, it is /usr/local/go, but you can change it if you installed Go somewhere else.
GOPATH: This is the location of your Go workspace, where you store your Go projects. You can choose any directory for your workspace, such as /go or /home/user/go.
PATH: This is the system variable that tells your system where to look for executable files. You need to add the Go bin directory to your PATH, so that you can run go commands from anywhere.
To set up these environment variables, you can use the export command in your terminal. For example, if you want to use /go as your workspace, you can run the following commands:
export GOROOT=/usr/local/go export GOPATH=/go export PATH=$PATH:$GOROOT/bin:$GOPATH/bin
These commands will only set the environment variables for the current session. If you want to make them permanent, you need to add them to your /.bashrc file, which is a script that runs every time you open a new terminal. To do that, you can use a text editor such as nano or vim to edit the file and append the export commands at the end of it. For example, using nano, you can run:
This will open the file in nano. Then, scroll down to the end of the file and add the export commands. Save and exit by pressing Ctrl+O and Ctrl+X. To apply the changes, you need to source the file or open a new terminal. To source the file, run:
Verifying the Go Installation
To verify that Go is installed correctly and that the environment variables are set up properly, you can use some go commands to check the version and configuration of Go. To check the version of Go, run:
The output should show the version of Go that you installed, such as:
go version go1.17.7 linux/amd64
To check the configuration of Go, run:
The output should show the values of the environment variables and other settings for Go, such as:
GO111MODULE="" GOARCH="amd64" GOBIN="" GOCACHE="/home/user/.cache/go-build" GOENV="/home/user/.config/go/env" GOEXE="" GOEXPERIMENT="" GOFLAGS="" GOHOSTARCH="amd64" GOHOSTOS="linux" GOINSECURE="" GOMODCACHE="/home/user/go/pkg/mod" GONOPROXY="" GONOSUMDB="" GOOS="linux" GOPATH="/home/user/go" GOPRIVATE="" GOPROXY=" GOROOT="/usr/local/go" GOSUMDB="sum.golang.org" GOTMPDIR="" GOTOOLDIR="/usr/local/go/pkg/tool/linux_amd64" GOVCS="" GOVERSION="go1.17.7" GCCGO="gccgo" AR="ar" CC="gcc" CXX="g++" CGO_ENABLED="1" GOMOD="/dev/null" CGO_CFLAGS="-g -O2" CGO_CPPFLAGS="" CGO_CXXFLAGS="-g -O2" CGO_FFLAGS="-g -O2" CGO_LDFLAGS="-g -O2" PKG_CONFIG="pkg-config" GOGCCFLAGS="-fPIC -m64 -pthread -fmessage-length=0 -fdebug-prefix-map=/tmp/go-build043434343=/tmp/go-build -gno-record-gcc-switches"
Getting Started with Go Programming
Now that you have installed and configured Go on your Ubuntu system, you are ready to start writing some code in Go. In this section, we will show you how to write a simple "Hello, world" program in Go and run it.
A Go program consists of one or more files with the .go extension, which contain the source code of the program. A Go file starts with a package declaration, which defines the name of the package that the file belongs to. The main package is the default package for executable programs, and it must contain a main function, which is the entry point of the program.
To write a "Hello, world" program in Go, create a file named hello.go in your workspace directory, and use a text editor to write the following code:
package main import "fmt" func main() fmt.Println("Hello, world")
This program imports the fmt package, which provides formatted input and output functions, and uses the Println function to print "Hello, world" to the standard output.
To run the program, you can use the go run command, which compiles and executes the Go file. In your terminal, navigate to the directory where you created hello.go, and run:
go run hello.go
The output should show the message "Hello, world".
In this article, you learned how to download and install Go 1.17 on your Ubuntu system. You also learned how to set up the Go environment variables and write a simple "Hello, world" program in Go. You are now ready to explore more features and applications of Go programming.
