If you are working in the internet with ubuntu, you may need some software to be installed before it is being used actually.

If you install ubuntu with a live CD, you will not have VLC Media player, etc.

Proxy setup needed to install/update software in ubuntu

1. proxy support for Synaptic package manager

Go to Settings-> preferences –> Network Tab, click manual proxy configuration and then set the proxy ip and port

2. proxy support for apt-get

Open the file /root/.bashrc and type the following line

export http_proxy=http://username:password@host:port/

If your proxy server does not have username/password combination then include the following line

export http_proxy=http://host:port/

for example,

export http_proxy=http://192.168.0.10:808/

(NB: .bashrc file is available for all the users of ubuntu, for example if the Linux user login name is “pradeepkumar” then there will be a .bashrc file at /home/pradeepkumar/, but setting the http_proxy in those files will be of no use, because ubuntu allows installation/upgrading of software only for super users ie root, so /root/.bashrc alone will be set with the http_proxy variable)
