Possible fixes to apt-get host resolution problems

/etc/nsswitch.conf :

hosts: files mdns4_minimal [NOTFOUND=return] dns mdns4

Replace it with :

hosts: files dns

Restart network:

sudo /etc/init.d/networking restart

if !work , add to /etc/hosts :

91.189.88.46 ca.archive.ubuntu.com

Restart network again



---------

Check your "/etc/resolv.conf" file. It should have the name servers mentioned


nameserver 208.67.222.222
nameserver 208.67.220.220

To check if it works do the following. Type 'nslookup' and press enter:

> server

ping -c2 74.125.45.100
