How To Install Git On Debian 10 Buster

Git is the world’s famous distributed software version control system that allows you to keep track of your software at the source level. It is used by many open-source and commercial projects. In this tutorial, we will be discussing completely how to install & get started with Git on Debian 10 Buster Linux along with the introduction of Git such as what is git, git terms, git commands, and also features of git.

What is Git?

Git is the most commonly used distributed version control system in the world created by Linus Torvalds in 2005. The popular option among open-source and other collaborative software projects is Git. Also, several project files are kept in a Git repository, and big companies like GitHubGitlab, or Bitbucket assist to promote software development project sharing and collaboration.

Mainly, the Git tool is utilized by development teams to keep track of all the changes happening on a codebase, as well as organizing code in individual branches. In today’s tutorial, we are working on how to set up Git on a Debian 10 Buster machine.

What is Debian?

Debian is an operating system for a wide range of devices including laptops, desktops, and servers. The developers of Debian will provide the security updates for all packages for almost of their lifetime. The current stable distribution of Debian is version 10, codenamed buster. Debian 10 is brand new, so if you require a complete setup tutorial for Debian 10, follow this tutorial.

Terms of Git

For a better understanding of Git, you must know a few of the common Git Terms. So, we have compiled here in detail:

  • Repository: It is a directory on your local computer or a remote server where all your project files are kept and tracked by Git.
  • Modified: If you add a file in the staging area, and modify the file again before committing, then the file will have a modified status. You will have to add the file to the staging area again for you to be able to commit it.
  • Commit: It is keeping a snapshot of the files that are in the staging area. A commit has information such as a title, description, author name, email, hash, etc.
  • Staged: Before you commit your changes to the Git repository, you must add the files to the staging area. The files in the staging area are called staged files.
  • Tracked: If you want Git to track a file, then you have to tell Git to track the file manually.
  • Untracked: If you create a new file on your Git repository, then it is called an untracked file in Git. Unless you tell git to track it, Git won’t track a file.

Steps for Installing Git From Source

As you probably noticed, you are not getting the latest version of Git with the apt repositories. As of August 2019, the latest Git version is 2.22.0. In order to install the latest Git version on your Debian 10 instance, follow those instructions.

Install required dependencies

In order to build Git, you will have to install manually dependencies on your system. To do so, run the following command:

$ sudo apt-get install dh-autoreconf libcurl4-gnutls-dev libexpat1-dev \
  gettext libz-dev libssl-dev

a – Install required dependencies manual-dependencies

Install documentation dependencies

In order to add documentation to Git (in different formats), you will need the following dependencies

$ sudo apt-get install asciidoc xmlto docbook2x

b – Install documentation dependencies manual-2

Install the install-info dependencies

On Debian configurations, you will need to add the install-info dependency to your system.

$ sudo apt-get install install-info

c – Install the install-info dependencies manual-3

Download and build the latest Git version

Head to the Git repository on Github, and select the version you want to run on your Debian instance.
d – Download and build the latest Git version latest-git-version

Head to the directory where you stored the tar.gz file, and run the following commands.

$ tar -zxf git-2.22.0.tar.gz
$ cd git-2.22.0
$ make configure
$ ./configure --prefix=/usr
$ make all doc info
$ sudo make install install-doc install-html install-info

Again, run the following command to make sure that Git is correctly installed on your system

$ git --version
