problem with wget in vps

Question

i install ubuntu-server 12.4 on my vps. i want to install virtualmin. when i trying to download [virtualmin]install.sh with wget, i saw this:

:/tmp# wget http://software.virtualmin.com/gpl/scripts/install.sh

--2013-11-27 23:26:03--  http://software.virtualmin.com/gpl/scripts/install.sh
Resolving software.virtualmin.com (software.virtualmin.com)... failed: Temporary failure in name resolution.
wget: unable to resolve host address `software.virtualmin.com'

what's the problem? and how can i fix it?
Thanks

I think this issue is raised due to DNS-related problem. You need to check the config file /etc/resolv.conf. It should contains entries like:

nameserver your.dns1.server.ip
nameserver your.dns2.server.ip

check if there is any thing strange in that..
