Ha, I'll just reply myself. I had an automated script to setup my computer and it turns out I don't need to brew tap caskroom/cask anymore. So, this was the solution:

brew untap caskroom/cask caskroom/versions

[vitorgalvao]

Go ahead and brew untap caskroom/fonts && brew tap homebrew/cask-fonts, as well.

thanks @vitorgalvao !
