How To Install Go Lang on Debian 11 / Debian 10


Go is a programming language designed by Google engineers Robert Griesemer, Rob Pike, and Ken Thompson. It is primarily intended to be a modern language: it doesn't have constructs that make you remember your past (like C's structs) or are inspired by other languages (like Python's list comprehensions).

Go's major features are: memory safety without a garbage collector, concurrency without data races, deadlock freedom, and coordination avoidance.

Here, we will see how to install Golang on Debian 11 / Debian 10.

Download and Install Go Language

Install wget package.
sudo apt update sudo apt install wget -y

Visit the Go Language download page to download the latest version of Go. Alternatively, you can download the Go language binary package via terminal using the following command.
wget https://golang.org/dl/go1.17.linux-amd64.tar.gz

Extract the archive to /usr/local.
sudo tar -zxvf go1.17.linux-amd64.tar.gz -C /usr/local/

Setup Go Environment

We will now configure the PATH environment variable to include Go's bin (/usr/local/go/bin) directory. To do that, execute the below command.

For the system-wide installation and load the environment onto your current login session, run the following command.
echo "export PATH=/usr/local/go/bin:${PATH}" | sudo tee /etc/profile.d/go.sh source /etc/profile.d/go.sh

For your specific profile and load the environment onto your current login session, run the following command.
echo "export PATH=/usr/local/go/bin:${PATH}" | sudo tee -a $HOME/.profile source $HOME/.profile

Verify Go Installation

Run the below command to see the version of the Go language.
go version

Output:
go version go1.17 linux/amd64

Check the Go environment variables we set in previous sections.
go env 

Output:
GO111MODULE="" GOARCH="amd64" GOBIN="" GOCACHE="/home/debian/.cache/go-build" GOENV="/home/debian/.config/go/env" GOEXE="" GOEXPERIMENT="" GOFLAGS="" GOHOSTARCH="amd64" GOHOSTOS="linux" GOINSECURE="" GOMODCACHE="/home/debian/go/pkg/mod" GONOPROXY="" GONOSUMDB="" GOOS="linux" GOPATH="/home/debian/go" GOPRIVATE="" GOPROXY="https://proxy.golang.org,direct" GOROOT="/usr/local/go" GOSUMDB="sum.golang.org" GOTMPDIR="" GOTOOLDIR="/usr/local/go/pkg/tool/linux_amd64" GOVCS="" GOVERSION="go1.17" 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-build1429786228=/tmp/go-build -gno-record-gcc-switches" 

Create First Project

Create a directory hello under your home directory.
mkdir -p hello cd hello

Let's create a simple program (hello) to test the Go installation.

vi hello.go

Place the following content in the hello.go file.
package main import "fmt" func main() { fmt.Printf("Welcome To ITzGeek\n") }

Now, run the code with the go command.
go run .

You would get the following greeting text.
Welcome To ITzGeek

Setup Debian 11 Official Repository In sources.list (/etc/apt/sources.list)

When you install Debian 11 using a DVD, the OS installer sets the DVD as the source for getting packages for your system if you didn't choose to scan for network mirrors. Due to this reason, the system would ask you to insert a DVD if the disc is not present in the DVD drive when you try to install any software.  Also, the packages on DVD may not be the latest release.  So, we need to get the packages from the Internet. Media change: please insert the disc labeled 'Debian GNU/Linux 11.0.0 _Bullseye_ - Official amd64 DVD Binary-1 20210814-10:04' in the drive '/media/cdrom/' and press [Enter] The /etc/apt/sources.list file with DVD as a source would look something like below. # deb cdrom:[Debian GNU/Linux 11.0.0 _Bullseye_ - Official amd64 DVD Binary-1 20210814-10:04]/ bullseye contrib main deb cdrom:[Debian GNU/Linux 11.0.0 _Bullseye_ - Official amd64 DVD Binary-1 20210814-10:04]/ bullseye contrib main deb http://security.debian.org/debian-security bullseye-security
