#3830 Homebrew tap README omits the brew trust step Homebrew 7 requires, so brew install swamp refuses the formula
Opened by reset · 10/23/2026
On a Mac with Homebrew 7.0.9, following the tap README (brew tap swamp-club/tap then brew install swamp) stops at Error: Refusing to load formula swamp-club/tap/swamp from untrusted tap. Homebrew 7 refuses third-party formulae until the tap is trusted. The README at https://github.com/swamp-club/homebrew-tap/blob/main/README.md (checked at the 20261020.024627.0-sha.26dc044f formula commit) has only the two lines brew tap swamp-club/tap and brew install swamp; grep -i trust README.md matches nothing. The manual's install page (/manual/how-to/install-swamp) lists only the curl ... | sh installer, so the README is the only place the Homebrew route is written down.
Expected: the README's install steps run to completion on a current Homebrew.
Actual: the second step refuses until the user discovers brew trust swamp-club/tap on their own.
Steps to reproduce:
- On Homebrew 7.x with no prior trust record for the tap,
brew tap swamp-club/tap. brew install swamp->Refusing to load formula swamp-club/tap/swamp from untrusted tap.brew trust swamp-club/tapthenbrew install swampsucceeds.
#738 (closed) is where the official tap was pointed out; it predates the Homebrew 7 trust requirement.
Suggestion: add brew trust swamp-club/tap between the tap and install lines in the README (and on the install page if a Homebrew section is ever added).
