Some observations and temporary workaround:

• brew upgrade seems to work fine despite the error.
• removing module blamed in the error resolved the error message.

Error:

/usr/local/Homebrew/Library/Homebrew/brew.rb (Cask::CaskLoader::FromInstalledPathLoader): loading minikube
Error: Unexpected method 'appcast' called on Cask minikube.
Follow the instructions here:
  https://github.com/Homebrew/homebrew-cask#reporting-bugs

Temporary Workaround:

brew uninstall minikube

[xand3r40r93]

Error: Unexpected method 'appcast' called on Cask vimmotion.

[bevanjkay]

In all of these cases, this is caused by having a Cask still installed in your Caskroom that was removed from homebrew-cask more than a couple of years ago. They were therefore never updated to remove the deprecated appcast stanza.
If you wish to keep the app installed, you may be best off removing the Cask from your Caskroom (however note that you won't be able to uninstall the app using Homebrew), as it will never receive updates or be able to be reinstalled in future.

rm -rfi $(brew --caskroom)/<token>

rm -rfi $(brew --caskroom)/winds

This will not remove the application from your computer.

Thanks for your guys help.

I received the same issue with adoptopenjdk:

brew uninstall ffmpeg

Error: Unexpected method 'appcast' called on Cask adoptopenjdk15.
Follow the instructions here:

Error: Unexpected method 'appcast' called on Cask adoptopenjdk8.
Follow the instructions here:
  https://github.com/Homebrew/homebrew-cask#reporting-bugs

Removing the caskroom entries using the instructions from @bevanjkay solved the issue.
