Network Internet settings in Ubuntu 12.04 - repairing after an upgrade

I preformed the usual upgrade to 12.04, and ended up loosing my Internet accessibility. Turns out you can corrupt the interfaces file in the etc/network directory.

To fix this, you need to make sure that the following content is present in "interfaces" file:

auto eth0
iface eth0 inet dhcp
auto lo
iface lo inet loopback

I found that the first two lines had been removed, and as a result, I could no longer connect to the Internet. I changed the file permissions using the following:

chmod 777 interfaces
