What is this "duplicate entry error"?

"I am trying to install Nucleus and I keep getting this error:

Error message was: "Error while executing query (INSERT INTO `nucleus_blog` VALUES (1, 'My Nucleus CMS', 'mynucleuscms', '', 1, 0, 0.0, '', 'http://localhost:8080/nucleus/', '', 5, 1, 0, 1, 1, 1, 1, 0)): Duplicate entry '1' for key 1";

What on earth does it mean and how can I fix it?"

One of your installation attempts has left one or more tables in your database. Go into myphadmin and delete all tables inside the database and reinstall.
