How to Install and Use Git on Ubuntu 20.04 LTS


In this article, I will take you through the steps to install and use Git on Ubuntu 20.04 LTS. Git is a free and open source distributed version control system available in most of the hardware platforms. Of all the version control system we have available today, git is the most commonly and most widely used version control system. It can be used to manage very small to very large projects very efficiently. It started with a tiny footprint in 2005 but it has now spreaded globally with the world wide use. Git allows and encourages you to have multiple local branches that can be entirely independent of each other. More on Git Official website.

Step 1: Prerequisites

a) You should have a running Ubuntu 20.04 LTS Server.

b) You should have sudo or root access to run privileged commands.

c) You should have apt or apt-get utility available in your System.


Step 2: Update Your Server

It is always a good idea to check for any latest available updates using apt-get update command to keep your System packages up to date.

root@localhost:~# apt-get update
Hit:1 focal InRelease
Get:2 focal-updates InRelease [114 kB]
Get:3 focal-backports InRelease [101 kB]
Get:4 focal-security InRelease [114 kB]
Get:5 focal-updates/main amd64 Packages [1,344 kB]
Ign:6 focal/mongodb-org/5.0 InRelease
Hit:7 focal/mongodb-org/5.0 Release
Get:8 focal-updates/main i386 Packages [562 kB]
Get:9 focal-updates/main amd64 DEP-11 Metadata [279 kB]
Get:10 focal-updates/universe amd64 Packages [875 kB]
Get:12 focal-updates/universe i386 Packages [647 kB]


Step 3: Install Git

There are multiple ways to install Git but we will look into the most easiest way that is by using apt-get package manager. As git package is available in the default Ubuntu Repository so it can be installed by running apt-get install git command as shown below.

root@localhost:~# apt-get install git
Reading package lists... Done

The following additional packages will be installed:
git-man liberror-perl
Suggested packages:
git-daemon-run | git-daemon-sysvinit git-doc git-el git-email git-gui gitk gitweb git-cvs git-mediawiki git-svn
The following NEW packages will be installed:
git git-man liberror-perl
0 upgraded, 3 newly installed, 0 to remove and 93 not upgraded.

After this operation, 38.4 MB of additional disk space will be used.

Step 4: Check Git Version

You can verify the git installation by running git --version command. If it shows output like below, then it confirms that git is successfully installed.

root@localhost:~# git --version
git version 2.25.1


Step 5: Setting Up Git

The next immediate step is to setup and configure the user name and email ID before performing any commit. This makes it easy to manage and track the number of commits done by multiple users on a branch. You can setup user name by using git config --global "User name" syntax and email ID by using git config --global "Email ID" syntax.

root@localhost:~# git config --global "CyberITHub"
root@localhost:~# git config --global ""

After setting up the user name and email ID, you can verify the details using git config --list command.

root@localhost:~# git config --list

All the configuration done through git command will save the information in a file called .gitconfig in the user's home directory. So you can also verify the configuration by checking this file using cat ~/.gitconfig command as shown below.

root@localhost:~# cat ~/.gitconfig
name = CyberITHub
email =


Step 6: Using Git

Now that we have setup Git, we can try using it by performing a git clone operations from GitHub. We can just clone a repository called wig by using git clone command as shown below. This will create a directory wig in your local system and copy all the contents from repository.

root@localhost:~# git clone
Cloning into 'wig'...
remote: Enumerating objects: 4240, done.
remote: Total 4240 (delta 0), reused 0 (delta 0), pack-reused 4240
Receiving objects: 100% (4240/4240), 4.47 MiB | 3.24 MiB/s, done.
Resolving deltas: 100% (2832/2832), done.

You can also check all the subcommands available with git command using git help -a command as shown below.

root@localhost:~# git help -a
See 'git help <command>' to read about a specific subcommand

Main Porcelain Commands
add Add file contents to the index
am Apply a series of patches from a mailbox
archive Create an archive of files from a named tree
bisect Use binary search to find the commit that introduced a bug
branch List, create, or delete branches
bundle Move objects and refs by archive
checkout Switch branches or restore working tree files
cherry-pick Apply the changes introduced by some existing commits
citool Graphical alternative to git-commit
clean Remove untracked files from the working tree
clone Clone a repository into a new directory
commit Record changes to the repository


Step 7: Uninstall Git

Once you are done using Git, you can think of removing this tool completely by using apt-get remove git command as shown below.

root@localhost:~# apt-get remove git
Reading package lists... Done
Building dependency tree
Reading state information... Done
The following packages were automatically installed and are no longer required:
git-man liberror-perl
Use 'apt autoremove' to remove them.
The following packages will be REMOVED:
0 upgraded, 0 newly installed, 1 to remove and 93 not upgraded.
After this operation, 36.5 MB disk space will be freed.
