Fix Certificate error with wget

So, you are unable to download from https sources with wget. Instead you get the following error.

ERROR: The certificate of \`www.google.com' is not trusted.
ERROR: The certificate of \`www.google.com' hasn't got a known issuer.

No problemo. This error is most likely occurring for missing root certificates. Simply install the ca-certificates package:

sudo apt-get install ca-certificates

This should work on Ubuntu and Debian derivatives.
