Were you ever stuck in a moment when you needed some application and you couldn't access the whole version just bunch of trials? Did you perhaps tried to use some alternative open source applications by now?  If  not don't worry. If yes, comment which ones because your suggestion might help someone who is in a search for some application but has no luck finding it.

So, In this article Ubuntu software center will be covered. You see, search for applications in Ubuntu will spare you some search time because Ubuntu has it's own software repository. You won't be lost in a sea of data gathered by search engines.

To open Ubuntu software center left click on an Ubuntu software center icon on a Launcher as shown on a figure 1.

After you have clicked on an Ubuntu software center icon you will be prompted with its interface as shown on figure 2.

Fiigure 2.  Ubuntu sofware center interface

After a brief introductory of an Ubuntu's software center interface it would be good to give you one example to make your app search easier. Let's say that you are a 3D designer. So far you have been using Maya or 3dsMAX. Suddenly you want to try something new and nothing comes up as a decent substitute.

To search 3D apps under Ubuntu software center you have to left click on a Graphics button, (on your left as you saw on figure 2 -  hint: where applications are grouped by certain area).

After you have clicked on a Graphics button you should be prompted with Graphics interface as shown on figure 3.

As seen on figure 3. next what you should do is  click on a 3D Graphics button. After that you will be prompted with 3D applications, as shown on a figure 4.,  which you will be able to install. Keep in mind already mentioned application ratings. So, pick one which is the most rated because there is a big chance that application is very good.  (But that  doesn't have to stop you to search a bit what other applications are offering and perhaps try them out).

I have chosen Blender since it is a very good application and I've been using it for quite some time. I'd say that it is a good open source alternative for Maya or 3dsMAX. You don't have to choose Blender if you don't want to. You can search a bit what other applications are offering. Just click on more info button below applications name and you will be prompted with application's description.

Note: After more info button you might have to click on a use this source button to get to the app's description. That doesn't go for all apps.

When you decide which application you would like to install just click on a  install  button with. That simple.

Important things that I would point out, for the end, considering Ubuntu software center are:

• Ubuntu software center is constantly updated and reviewed – so watch what's new.
• There are free applications and applications you can buy – it is your decision which ones will  you install.
• Applications that are brought to you in Ubuntu's software center have a support but not all of them are supported by Ubuntu nor Canonical but some third party instead – keep an eye on that support because you don't want to end up with software which is not up to date.
• To download software you have to be online – I will cover Internet connection while introducing you with Indicators which you were able to see on first article.

In the next article I will cover System settings.
