brew install markfluence prints a deprecation warning and tells me to report it to a tap that doesn't exist.
What I did
brew tap mozilla/markfluence https://github.com/mozilla/markfluence
brew trust mozilla/markfluence
brew install markfluence
What I got
Warning: Calling `postflight` is deprecated! Use `postflight_steps` instead.
Please report this issue to the mozilla/homebrew-markfluence tap (not Homebrew/* repositories), or even better, submit a PR to fix it:
/opt/homebrew/Library/Taps/mozilla/homebrew-markfluence/Casks/markfluence.rb:39
Two things about that message are confusing on their own:
- It says to report to
mozilla/homebrew-markfluence, which is a 404. The tap is mozilla/markfluence — the repo is its own tap — and homebrew-markfluence is only the directory name Homebrew uses locally.
- It points at a file with
# This file was generated by GoReleaser. DO NOT EDIT. at the top, so the suggested PR would be overwritten by the next release.
What I expected
A clean install with no warning.
Does it actually work?
Yes. The install completes, markfluence --version reports markfluence 0.1.0 (1d0a2d0, 2026-09-20), and shell completions work. It's noise, not breakage — but it's noise on the very first thing a new user does, and it reads like something is wrong with the project.
