Problem

Why is Git always asking for my password? How to setup GitHub to SSH access.

Solution

Setup your github account using the Terminal and SSH.

Step by step

  1. How to Install Git on Ubuntu 22.04 and 24.04 
     sudo apt update
 sudo apt install git
 git --version
  2. Tell to git who you are. 
     git config --global user.name "rogelioprieto"
 git config --global user.email "myname@googlemail.com"
 git config --list
 cat ~/.gitconfig
  3. Generate a new SSH key 
     ls -al ~/.ssh
 ssh-keygen -t ed25519 -C "myname@googlemail.com"
 eval "$(ssh-agent -s)"
 ssh-add ~/.ssh/id_ed25519
 gh ssh-key add ~/.ssh/id_ed25519.pub

  4. Copy the new SSH key into clipboard

    For Ubuntu:

    #copy the ssh key into clipboard
sudo apt-get install xclip
xclip -selection clipboard < ~/.ssh/id_ed25519.pub

    For Fedora 43 using wl-clipboard package

    #copy the ssh key into clipboard
wl-copy < ~/.ssh/id_ed25519.pub < ~/.ssh/id_ed25519.pub
  5. Paste the new SSH key to your GitHub account, follow these steps: https://docs.github.com/en/authentication/connecting-to-github-with-ssh/adding-a-new-ssh-key-to-your-github-account

  6. Connect to and clone the repository

     #Test ssh connection
 ssh -T git@github.com
 #make dir and clone
 mkdir ~/github
 cd ~/github/
 git clone git@github.com:rogelioprieto/linux-tips.git
 ls -la
 cd linux-tips
 git status
  7. Finally, you can edit or create a file and push into the repository 
     git add .
 git status
 git commit -m "added minor changes"
 git push -u origin master
 git status

    or you can use these commands in one line:

     git add . && git commit -m "added minor changes" && git push -u origin master
