On windows if you're the administrator running and installing an application is easy. in ubuntu launching an application requires an administrative privileges..

can someone enlighten me please, how do i go about this?

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

Please add the information regarding how you tried to install an application in Ubuntu, i.e, is it via Ubuntu software center, commandline, or some other method? – saji89 Mar 14 '13 at 7:26
Put your password in the window. When ubuntu is asking for password, that means you are doing something sensitive. You should know what you are doing before doing it. – Web-E Mar 14 '13 at 7:28

You can become admin in Ubuntu with sudo -i. If you want to launch any application as root then application can be launched as follows

sudo application_name

If it is a GUI application then launch it with

gksudo application_name

Installing application can be done from apt-get ,aptitude,Software center , synaptic package manager.

From apt-get

sudo apt-get install application_name

From aptitude

sudo aptitude install application_name

Software center and synaptic are GUI applications.

NOTE: You should have clear knowledge on which application can be launched as admin.

hai jai, thanks, so everytime i launch an app from the terminal i have to add sudo? can't i give the privilege for good so next time i launch app with using sudo? – jeret Mar 14 '13 at 7:52
If you want to launch the app as admin then you must use sudo before the application name. – Raja Mar 14 '13 at 8:06
@jeret, you could do that with the use of aliases. Just go into your .bashrc file in your home folder and put an alias there to run whichever command you wish to run as root. For example: If you wish to run 'apt-get' as root always, you can add the line "alias apt-get='sudo apt-get'". You might need to restart the terminal for this to take effect. Hope this helps :) – Chirag64 Mar 14 '13 at 8:11
@Chirag64 actually to update the changes of bashrc we need to do source ~/.bashrc – Raja Mar 14 '13 at 8:13
@Jai, You can do that to apply the changes in the current terminal instance itself. But if you start a new instance, it will automatically apply the configured changes from .bashrc everytime it starts. – Chirag64 Mar 14 '13 at 8:18
