Are you new to Ubuntu? Did you hear about Ubuntu from a friend and want to try it out?  Are you trying to start using Linux in your computer but need help getting started? In this section you will find everything you need to know to get familiar and get started using Ubuntu.

What is Ubuntu?

Ubuntu is a Linux Desktop/Server Distribution developed by a small group of developers funded by Mark Shuttleworth in 2004. In 2005 Shuttleworth founded the Ubuntu Foundation and made an initial investment of 10 million dollars to ensure the long term support of the project. Nowadays Ubuntu is largely developed and supported by volunteers from around the world taking responsibility for many critical elements of the project. Ubuntu is licensed under the GPL license, and its free to use and distribute for everyone as long as the license agreement is respected.

Ubuntu Releases

Ubuntu is released on a predictable six-month basis. It was decided that every fourth release, issued on a two-year basis, would receive long-term support (LTS). LTS releases are typically used for large-scale deployments, and by users that want more stability in the OS than using cutting edge technologies. An Ubuntu LTS release is supported for 5 years after being released. A standard Ubuntu release is supported for 9 months after being released. Ubuntu LTS releases tend to be conservative in new features focusing instead on stability, while the short term support releases tend be more cutting edge packed with new features and innovation.

Ubuntu Flavors

There are 10 different Ubuntu flavors; each with its own desktop environment ( DE ). A Desktop Environment is a set of programs and applications with which the user interact with in his or her computer. The underlying platform in all Ubuntu flavors is the same, just the Interface the user interact with is different. The most popular desktop environments in Linux are Gnome, KDE, XFCE, and LXDE.

  • Ubuntu – Official Ubuntu release with the Unity Desktop
  • Edubuntu — Ubuntu for education
  • Ubuntu GNOME — Ubuntu with the GNOME desktop environment
  • Kubuntu — Ubuntu with the K Desktop environment
  • Ubuntu Kylin — Ubuntu localized for China
  • Lubuntu — Ubuntu that uses LXDE
  • Mythbuntu — Designed for creating a home theatre PC with Myth TV
  • Ubuntu Studio — Designed for multimedia editing and creation
  • Xubuntu — Ubuntu with the XFCE desktop environment
  • Ubuntu MATE — Ubuntu with the MATE desktop environment

What is the best Ubuntu flavor for me?

If you are new to Linux then the official Ubuntu release with the Unity Desktop will be the best for you to use. The Unity Desktop is professionally designed and meant to be used by non-technical computer users. Linux always has been an operating system used by computer nerds only, but Ubuntu is the first Linux distribution that tries to bring Linux to the masses. Ubuntu is the most popular Linux distribution used in desktops and laptops.

Ubuntu Server

Because Ubuntu Server has no desktop environment, there is only one official flavor of Ubuntu for servers.

Its surprising but Microsoft is playing nice with the open source community now, they are making some of their software available on Linux. They started with .NET and now SQL, I guess their mantra now is “if you can’t beat them, join them.

If you need to back up your Ubuntu servers to a Windows share on your network,  then on this tutorial I will show you how you can accomplish that. This tutorial is based on Ubuntu, but the procedure should work in all Linux distributions. I have a Centos server that I backup using this script as well. Create the Windows share The first thing you need to do is to create the Windows share where the Ubuntu backup files will be dumped to. For example, I created a shared folder in my windows server called “LinuxBackup” for this backup. Create the user account for the Windows share You need to create either an AD or local user account to use for this backup, and add that user to the Windows share you created above with give it at least read/write…

Ubuntu server 16.04 still fits in a CD-RW )   I’m using…

If when browsing your website you come across directories that looks like this: then directory listing is enabled in your web server. I believe in Ubuntu directory listing is enabled by default when you install Apache. I don’t know why this is enabled by default, because it might be a security issue, and might slow down the web server performance as well. to disable directory listing in Ubuntu, just SSH to your web server and run this command: sudo a2dismod autoindex then reload apache: sudo service apache2 reload that’s it. now directory listing should be disabled in your web server, and when trying to access any directory on your web server from you browser,  you should get the following error now:

I use Ubuntu on my computer, at work and at home. Sometimes I like to watch live TV channels like History or CNN on my browser, but in Ubuntu it was a no no when I tried it. But after a couple of minutes of googling I was able to get it running. here is what you need to do to watch live channels like CNN, History, and Amazon videos online . please keep in mind that this instructions will only work on Firefox, it won’t work on Google Chrome, and I haven’t try in any other browser so I don’t know.

In Ubuntu just install the entire proprietary media codecs, flash and Microsoft fonts by typing this on terminal sudo apt-get install ubuntu-restricted-extras accept all the agreements that come up. I don’t know…

Microsoft Exchange is very popular in businesses for email, contacts, and calendar management. Now with the cloud hype, many businesses are moving to Google Apps ( good for them ) and others to Office 365 which is basically an Exchange server hosted in a Microsoft data center. when you switch operating system from Windows to Linux and need to use Exchange for email and calendar every day, it becomes a struggle trying to tweak or find a Linux email client to replace Outlook. pretty soon you find out that there is no other email client that can replace Outlook when using exchange, because Exchange and Outlook are built for each other, so trying to find a client that behaves and work the same way as Outlook in Linux is a fruitless effort. In Linux there is Evolution and Thunderbird for…

If you are new to Linux then you probably already noticed the disparity among Linux users when it comes to choosing what desktop to use.  You will hear from KDE users that KDE is the best and you should use that, likewise GNOME users will swear that gnome is the real deal. then there are the traditionalists that prefer desktop environments like XFCE, Cinnamon, and MATE. Many people see this diversity in Linux as a bad thing, but in reality that is what makes Linux so great. In Linux the user is in charged not the other way around. The default interface in Ubuntu is called Unity and its a shell for the GNOME default desktop. There might be a confusion between a desktop shell and a desktop environment for newcomers, but in a nutshell ( no pun intended )…

If you are planning to replace Windows with Ubuntu then the first thing you need to do is to think about what you need the computer for? Do you need to use office applications like Microsoft Office, Photoshop, Illustrator, etc.? or you just need the computer to browse the Internet? I think answering those questions is important before making the switch from Windows to Ubuntu because from that will depend your adaptation to Ubuntu. Pros of using Ubuntu No Viruses, and good security Easy software management Very Fast Nice looking design Less learning curve than other Linux distributions Good Privacy Open Source Cons of using Ubuntu Not good for gaming No Microsoft applications Need to use the Linux terminal to do certain things Some Hardware might lack drivers support   Some people install Ubuntu alongside Windows , and boot to…
