How to install git-annex on Ubuntu 17.04

How to install Git-annex on Ubuntu 17.04

The Git-annex allows managing files with Git, without checking the file contents into Git. It aims to solve the problem of sharing and synchronizing collections of large files independent from a commercial service or even a central server. This tutorial explains the installation procedure of Git-annex on Ubuntu 17.04. 

 

Installation procedure

To start the installation process, add the required repo by executing the following command. 

root@linuxhelp1:~# add-apt-repository ppa:eugenesan/ppa
This repository contains collection of customized, updated, ported and backported
packages for two last LTS releases and latest pre-LTS release.
Packages for older releases relocated to ppa:eugenesan/archive or deleted.
