Step 2: Downloading Go

Now, navigate to the official Go website to find the latest version of the language. Copy the download link for the Linux distribution. In your terminal, use wget to download the Go tarball:

wget https://golang.org/dl/goX.XX.X.linux-amd64.tar.gz

Replace X.XX.X with the latest version number available.

Step 3: Extracting the Tarball

Once the download is complete, extract the tarball using the following command:

sudo tar -C /usr/local -xzf goX.XX.X.linux-amd64.tar.gz

Step 4: Configuring Environment Variables

To use Go, you need to set up the PATH and GOPATH environment variables. Edit your profile configuration file using a text editor like nano:

nano ~/.profile

Add the following lines at the end of the file:

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

Save and exit the text editor. Then, apply the changes to your current session:

source ~/.profile

Step 5: Verifying the Installation

To verify that Go has been installed successfully, run the following commands:

go version

You should see the installed Go version printed in the terminal.

Add the following line to your profile configuration:

[[ -s "$HOME/.gvm/scripts/gvm" ]] && source "$HOME/.gvm/scripts/gvm"

Source your profile or restart the terminal:

source ~/.profile

Installing Specific Go Versions

With gvm, you can easily install and switch between different Go versions. To install a specific version, use the following command:

gvm install goX.XX.X
