How to Configure SSH Key for GitHub on Ubuntu

As we previously learned how to Run the Ubuntu machine on Windows 10 using VsCode Extension WSL. Incased you missed it please learn from this blog.

How to Configure SSH Key for GitHub on Ubuntu

Prerequisites:

  • Ubuntu Machine
  • Git
  • Linux basic Commands

Git Installation or Version check

As Git is pre-installed in git you can check by entering the following command

git --version
git — version

In case if git is not installed in your Linux system you can install by using the following commands

sudo apt-get update
sudo apt-get install git

and after these following commands you can check your git installation by the first command we execute in this blog

git --version

Creating Private and Public SSH Keys

First, we need to create private and public keys. Please do not share your private key on any platform. Please only share the id_rsa.pub key on GitHub

mkdir .ssh
cd .ssh
ssh-keygen -t rsa -b 4096
ssh keys for GitHub

so the ssh keys are generated inside your /home/adil/.ssh/id_rsa (please change adil username to your username you are using)

Now, you have to add the public SSH Key into your SSH Agent:

sudo ssh-add /home/<your username>/.ssh/id_rsa

Sometimes, depending on your Linux configuration, you could have the message “Could not open a connection to your authentication agent.”. In that case, you should execute:

eval `ssh-agent -s`

Configure SSH Key for GitHub on Ubuntu

Profile Pic/Settings/SSH and GPG Keys

Then Press on the New Key

Go back to the terminal and enter the following command. You need to copy the following command and please do not share with any person or platform.

cat ~/.ssh/id_rsa.pub

Copy the content, paste it in the GitHub Form and press the “Add SSH Key” button

This is totally fake

Finally, we need to check that our SSH is working or not by entering the following command

ssh -T git@github.com

Hurrah Finally we configure our SSH on Github and Ubuntu Machine.
