How can I fix a 404 Error using a PPA?

When I run sudo apt-get update && sudo apt-get dist-upgrade, I get the following:

You need to fix your sources.list file. Try opening the terminal Ctrl+Alt+T. Next type sudo gedit sources.list . The sources list will pop-up. Remove the ones listed which appear to no longer be valid. You'll also need to edit the entries in /etc/apt/sources.list.d . To edit these you can type sudo nautilus to open the file browser as root and delete the ppa's listed in the errors above. Replace with actual valid sources and save. Run the update command to refresh and get the updates.
