Unexpected method 'appcast' called on Cask winds about homebrew-cask HOT 8 CLOSED

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.

Some observations and temporary workaround:

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

Unexpected method 'appcast' called on Cask adoptopenjdk11.

Had the same. I ended up deleting the adoptopenjdk manually then reinstall if needed, but this one is being deprecated for temurin.

I'm having the same issue but it's complaining about a font installed from the (cask-fonts)[https://github.com/Homebrew/homebrew-cask-fonts/] tap. But I can't try the workaround because brew uninstall isn't working, even on other casks/formula.

Edit: Uninstall issue was unrelated
