Dig on Ubuntu 12.04

Is Dig not installed on your Ubuntu box? Ask the internets and it'll say: just install dnsutils, easy!

# apt-get install dnsutils
# Package dnsutils is not available, but is referred to by another package....

Not so easy...
Anyway the magic fix is to update your package index:

# apt-get update


You should then be able to run the below as normal:

# apt-get install dnsutils



Now your package index is up to date you can also upgrade all your packages with:

# apt-get upgrade

Also useful to remember, if you end with a broken package, just run:

# apt-get -f install
