It seems to be suggesting that what you have in ~/adaptbuilder/adapt_florida is not a git repository

When you did the original install, did you $ git clone the adapt authoring project, as documented here?

Have a look in that folder, does it have a subfolder called .git? You might need to do ls -lah from the terminal to make sure it shows you all files & folders - the . at the start of the folder name makes it a 'hidden folder'
