I have a raspberry pi 2 running raspbian, and bought a wifi dongle to use with it. I can't seem to get it connect to the internet. I have tried following the guide given by the seller, but it was written for Headed units, and I want to go headless. I also tried using sudo raspi-config to set up the internet.
output of ifconfig
output of lsusb

First thing that seems to be wrong is what Wifi dongle you are using. I suggest purchasing the following: https://www.ebay.com.au/itm/Edimax-EW-7811Un-WiFi-N150-USB-Adapter-for-Linux-MacOS-Windows-Raspberry-Pi/172798424298?hash=item283b96b4ea:g:KowAAOSwjS9ZfDpM:rk:1:pf:0 If your dongle is not driverless, you can't use it. Also, after connecting first try to use the GUI to connect to the internet. The GUI wifi button is in the top right hand corner. If that doesn't work, get your Wifi config app onto your desktop to use it. That allows for you to easily connect to the internet. If all that doesn't work, I point you to the following post: How do I set up networking/WiFi/static IP address?
This goes in detail in how to connect to the internet. If you could also update what are the results for the inputs sudo nano /etc/dhcpcd.conf and lsusb and ifconfig that would make the question clearer.
