What are you specifically trying to install? – cloyd800 Apr 25 '12 at 6:54
Can you copy/paste the command you use. Something seems to be wrong there. – mikewhatever Apr 25 '12 at 7:09
When i used the code sudo apt-get update i get the below "something wicked happened in resolving "in.archive.ubuntu.com ".... (5 - no address associated with hostname ) " – Amirtham Purendra Raman B Apr 25 '12 at 8:54

E: Unable to locate package update

some times it happens when you have internet connection with proxy. I have encountered the same case with me. Please also check that you are proxy free and configured it so that proxy server allows you.

Code: sudo apt-get update if it runs, then everything could be installed. And Please mention what you are trying to update here... the solution can vary a bit. :)

Edited:

Seems like your DNS configuration is unable to resolve the address.Try pinging to this server from Windows/any other Linux DNS Client.It will inform you with IP.Put that IP under /etc/hosts or under /etc/apt/source.list instead of hostname. Do Check /etc/resolv.conf too.

Sounds like a DNS problem. Try putting:

nameserver 8.8.8.8
nameserver 8.8.4.4

In /etc/resolv.conf and putting:

dns-nameservers 8.8.8.8 8.8.4.4

In /etc/network/interfaces.
