If you are sure that you have a good network connection, you may have to
select a different mirror. The Ubuntu mirrors have problems on occassion
(more than they should) but generally clear up after a short while. More
than likely your host file is messed up (common on Hardy install); ping
the mirror:

~$ ping de.archive.ubuntu.com
PING ubuntu.mirror.tudos.de (141.30.3.82) 56(84) bytes of data.
64 bytes from tethys.zih.tu-dresden.de (141.30.3.82): icmp_seq=1 ttl=52
time=183 ms

and if its working try again.

If it can't resolve the host try 'ping localhost'. If that doesn't work,
then from a terminal:

nano /etc/hosts

change to:

127.0.0.1 localhost <computername>
127.0.1.1 <computername>

Nothing else on those two lines, particularly if you see:

127.0.1.1 <computername>.<workgroupname>

be sure to drop the .<workgroup> bit.

Note: for <computername> use the name in /etc/hostname:

cat /etc/hostname

Then:

sudo /etc/init.d/networking restart

ifconfig

make sure that you have a valid network IP/interface showing up.

then

ping localhost
ping google.com
ping de.archive.ubuntu.com

If that works:

sudo apt-get update
sudo apt-get upgrade

After that reboot & try your failsafe mode again.
