Homebrew Tap is broken

[rsdy]

I get the following response from brew update:

Error: Fetching /opt/homebrew/Library/Taps/filippo.io/homebrew-yubikey-agent failed!

Trying to untap/retap will result in a password prompt for Github.

Thank you for the report. I added back a master branch with just the Homebrew Formula, and I will replace it with a Tap migration entry once Homebrew/homebrew-core#71440 is merged.

Could you try a brew update and check if it's working?

brew install yubikey-agent                                                                                                                            <update_wp_core ✗>

@FiloSottile I still get a password prompt when I brew tap filippo.io/yubikey-agent:

% brew tap filippo.io/yubikey-agent

New brew tap invocations are broken and will not get fixed, once Homebrew/homebrew-core#71440 is merged brew install yubikey-agent will just work without the custom tap. What was fixed and verified by another reporter is brew update for existing taps.
