If you are unable to ping other hosts, you need to check your resolv.conf file and ensure that proper name servers are listed.
What is the contents of your /etc/resolv.conf ? This is a DNS resolution problem so your provider has provided you with non functioning resolvers most likely or none at all. You could add the following to the /etc/resolv.conf to solve the problem for the time being: nameserver 4.2.2.1 nameserver 4.2.2.2 These are level3 resolvers. I would not advise using them as a permanent solution though they're not always reliable.
I'm showing this as a direct link from the one you gave: http://downloads.sourceforge.net/project/webadmin/webmin/1.470/webmin_1.470_all.deb That works for me with a wget.
