Installing Git on Linux

Determine on which Linux distribution your system is based on. See List of Linux distributions – Wikipedia for a list. Most Linux systems – including Ubuntu – are Debian-based.

Debian-based linux systems

Open a terminal window. Copy & paste the following into the terminal window and hit Return. You may be prompted to enter your password.

sudo apt update
sudo apt upgrade
sudo apt install git

You can use Git now.

Red Hat-based linux systems

Open a terminal. Copy & paste the following into the terminal window and hit Return. You may be prompted to enter your password.

sudo yum upgrade
sudo yum install git

You can use Git now.

Installing Git on a Mac

Open a terminal window.

Step 1 – Install Homebrew

Homebrew […] simplifies the installation of software on the Mac OS X operating system.

– Homebrew – Wikipedia

Copy & paste the following into the terminal window and hit Return.

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"
brew doctor

You will be offered to install the Command Line Developer Tools from Apple. Confirm by clicking Install. After the installation finished, continue installing Homebrew by hitting Return again.

Step 2 – Install Git

Copy & paste the following into the terminal window and hit Return.

brew install git

You can use Git now.

Installing Git on Windows

1. Download Git from Git for Windows and install it.

when i want to send my code to my repository --> "git push -u origin main"

this appears, but why they continue ask me about password if they already not accept.
and i been trying whit ssh keys and can not do it also.

some idea...

remote: Support for password authentication was removed on August 13, 2021. Please use a personal access token instead.
remote: Please see https://github.blog/2020-12-15-token-authentication-requirements-for-git-operations/ for more information.
fatal: Authentication failed for 'https://github.com/duarteing/globalduarte.github.io.git/'

First, you need to create a personal access token (PAT). Why? The process is described here: Creating a personal access token

Using a token on the command line

Once you have a token, you can enter it instead of your password when performing Git operations over HTTPS.

For example, on the command line you would enter the following:

$ git clone https://github.com/username/repo.git
Username: your_username
Password: your_token

Personal access tokens can only be used for HTTPS Git operations. If your repository uses an SSH remote URL, you will need to switch the remote from SSH to HTTPS.

If you are not prompted for your username and password, your credentials may be cached on your computer. You can update your credentials in the Keychain to replace your old password with the token.

Instead of manually entering your PAT for every HTTPS Git operation, you can cache your PAT with a Git client. Git will temporarily store your
credentials in memory until an expiry interval has passed. You can also store the token in a plain text file that Git can read before every
request. For more information, see "Caching your GitHub credentials in Git."

@hadiheib99 You don't mention the entire apt readout, but one of your packages may be broken.

Here are a few things you can try (run sudo apt update after each).

Method 1: Reconfigure Package Database

The first method you can try is to reconfigure the package database.
Perhaps the database got corrupted while installing a package.
Reconfiguring often fixes the problem.

sudo dpkg --configure -a

Method 2: Use force install

If a package installation was interrupted previously, you may try to do
a force install.

sudo apt install -f

Method 3: Try removing the troublesome package

If it’s not an issue for you, you may try to remove the broken package
manually. Don’t do this for Linux Kernels (packages starting with
linux-).

sudo apt remove <package_name>

Method 4: Remove post info files of the troublesome package

This should be your last resort. You can try removing the files
associated to the package in question from /var/lib/dpkg/info.

You need to know a little about basic Linux commands to figure out
what’s happening and how can you use the same with your problem.

For example, you had an issue with polar-bookshelf. You would look for the
files associated with it:

ls -l /var/lib/dpkg/info | grep -i polar-bookshelf
-rw-r--r-- 1 root root 2324811 Aug 14 19:29 polar-bookshelf.list
-rw-r--r-- 1 root root 2822824 Aug 10 04:28 polar-bookshelf.md5sums
-rwxr-xr-x 1 root root     113 Aug 10 04:28 polar-bookshelf.postinst
-rwxr-xr-x 1 root root      84 Aug 10 04:28 polar-bookshelf.postrm

Now all I needed to do was to remove these files:

sudo mv /var/lib/dpkg/info/polar-bookshelf.* /tmp

Use the sudo apt update and then you should be able to install software
as usual.

thank you

I have tried installing homebrew via mac os terminal, but it keeps asking me for a password. does anyone know which password this is? it comes up as a key sign.

its your computer's administrator password

Just confirmed that macOS instructions still work ! 🗡️

It worked in Ubuntu
Thank you

thank you
