brew cask list fails if previously installed but now unavailable cask

[mrkev]

Description of issue

1. I run brew cask list
2. I get output with a few warnings (usual, outdated casks), and also this:

Error: Cask 'utorrent' is unavailable: No Cask with this name exists.

3. brew cask list exits with status code 1, and never prints the casks I have installed

brew cask uninstall | install | zap also print Error: Cask 'utorrent' is unavailable: No Cask with this name exists. and exit with status code 1. I'm unsure how to fix this so brew cask forgets about utorrent and I can list my casks again.

Output of your command with --verbose --debug

Note, I don't think the warnings are consequential, but including them for for the sake of full information.

Removing the utorrent folder from /usr/local/Caskroom should fix this.

[mrkev]

That did it. Thanks! 👍
