GitHub installation in Ubuntu

First things first, you need to create a GitHub account @ https://github.com/.

Open the Ubuntu terminal and run the following command to update/upgrade the existing packages

sudo apt-get update && sudo apt-get upgrade

and the following command to install GitHub

sudo apt install gh

In case of error, as in this case

check that the resolv.conf file is in the /etc directory

cd /etc

ls -la

If the file is missing, create it:

sudo nano resolv.conf

Add the following entries to resolv.conf file:

To close the file, press Ctrl + x

then y

and finally press the Enter key.

Let’s try to install GitHub again. This time the installation should be successful.

sudo apt-get update && sudo apt-get upgrade

sudo apt install gh

Create an SSH key

 ssh-keygen -t rsa -b 4096

Create a config file in the ~/.ssh directory

cd .ssh

 sudo nano config

The command above has created and opened the config file. Add the following entries to the config file:

# GitHub:
Host github.com
HostName github.com
IdentityFile ~/.ssh/id_rsa_github
User git

To close the file, press Ctrl + x

then y

and finally press the Enter key.

id_rsa_github is the name of the file where the ssh will be saved; you can call it whatever you like, e.g. id_rsa_github_your_username

Log in to GitHub from the Ubuntu terminal

The ssh key is added to your GitHub account at this point.

To log in, enter the following command:

 gh auth login

Create an authentication token at https://github.com/settings/tokens

Once you have the token, paste it in the Ubuntu terminal to complete the login process:
