Github failure message related to cask

[codingbutstillalive]

Dear fellows,

I just had a fresh install of homebrew. When I run

brew install --cask rectangle

it gives me the following output:

Error: Failure while executing; git clone https://github.com/Homebrew/homebrew-cask /usr/local/Homebrew/Library/Taps/homebrew/homebrew-cask exited with 128.

How to fix that? :)

What happens when you run brew tap homebrew/cask? Please post the full output here.

After executing this command, I tried again to install "rectangle" and this time it worked.
