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'
