A Guide on How to Install Ubuntu 15.04 with Screenshots

Ubuntu is a Debian based Linux operating system for servers, desktop computers, tablets, phones and TVs. Word Ubuntu means humanity or humanity to others. A UK based company Canonical Ltd led by a South African entrepreneur Mark Shuttleworth is developing Ubuntu but it is an open source product so further customizations or modifications can be done by anybody. Ubuntu is getting great popularity among the PC users because of being free of cost, lightweight and ease of use through legacy desktop.

Ubuntu is more secure and less vulnerable to Viruses and Trojans because of its custom configurations, less privileged and more privileged (super user/root) divide, implementation of Polkit (short for policy kit: it controls system wide privileges and provide a mechanism for communication between less privileged processes and more privileged processes), most of the network ports are blocked by default and so on.

Main Features

Ubuntu comes with few very nice set of preinstalled features. We will have a glance at few but not all here.

LibreOffice is a free open source office suite which comprises of word processing, spreadsheets, slidshows, drawing and diagrams. It also maintains databases and compute mathematical formulae. LibreOffice follows the international standard ISO/IEC open document file format so it is compatible with major competitors like OpenOffice, MS Office, etc.

Mozila Firefox is an open source cross platform web browser. It is fast and feature rich web browser occupying from 12% to 20% of desktop usage and considered to be world’s third largest browser being used.

Mozila Thunderbird is another wonderful product from Mozila Fountation which is open source and freely available for almost all platforms. Mozilla Thunderbird is an email client with historically studded with enormous features but now further development for new features has been limited because the investments made are not showing desired incentives.

Transmission is free bit torrent software under GNU General Public License (GNU GPL) which is cross platform and has a simple interface.

Upgrading from Ubuntu 14.10 to Ubuntu 15.04 Server From CLi

Ubuntu releases its LTS (Long Term Support) version every two years. If you want to upgrade to Ubuntu 15.04 which is not LTS then we will have to tell the upgrade manager to upgrade from a Ubuntu LTS 14.04/14.10 to normal Ubuntu 15.04 release.

Run the following command in terminal to install the core update manager on the system.

sudo apt-get install update-manager-core

Once done, we need to tell system to upgrade from an LTS version to a normal release, to do so we need to edit the release config file using the following command.

sudo gedit /etc/update-manager/release-upgrades
LTS or Normal

Now find the label "Prompt=LTS" and changed it to "Prompt=normal" and save the changes made to the file so that we can upgrade to a non-LTS version of ubuntu i.e Ubuntu 15.04 Vivid Verveta.

in File

Run the following command to update apt-get repository.

sudo apt-get update
update apt

Finally run the below command to upgrade to latest release of Ubuntu.

sudo do-release-upgrade

update ubuntu
