can't install webmin on ubuntu server

Question

I have an Ubuntu server installed and I want to install webmin on it but I can't. I have tried everything but reached no solution. I also set this

deb http://download.webmin.com/download/repository sarge contrib
deb http:// webmin.mirror.somersettechsolutions.co.uk/repository sarge contrib 

in /etc/apt/sources.list. Can someone help me?

Here is the detail of the problem:

t@aksoy:~$ wget http://prdownloads.sourceforge.net/webadmin/webmin_1.700_all.deb
--2014-08-18 21:31:47--  
http://prdownloads.sourceforge.net/webadmin/webmin_1.700_all.deb
Resolving prdownloads.sourceforge.net (prdownloads.sourceforge.net)... failed: Name or service not known.
wget: unable to resolve host address ‘prdownloads.sourceforge.net’

PS: Sorry for my bad English

Solution

Just add

deb http://download.webmin.com/download/repository sarge contrib

in your sources.list and run the command

wget -q http://www.webmin.com/jcameron-key.asc -O- | sudo apt-key add -

to import the key
after that

apt-get update
apt-get install webmin

this is a good tutorial at UbuntuHandbook
