i just get my new web server (Ubuntu 10.04) at Leaseweb and when i try to install Virtualmin i get this error :

wget --2012-02-11 13:53:03-- Resolving failed: Temporary failure in name resolution. wget: unable to resolve host address `'

I already do apt-get install build-essential and when i try to re-install wget i have :

apt-get install wget Reading package lists... Done Building dependency tree Reading state information... Done wget is already the newest version. 0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

Ping and host also dont working

host ;; connection timed out; no servers could be reached

Any idea ?

It is clear that you have 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

By the way, re-installing wget has nothing to do with the problem. Also, using host command confirms this problem.
