Homebrew 7 CI: Homebrew/actions@master removed and ghcr.io/homebrew/ubuntu22.04 image removed
# before
- uses: Homebrew/actions/setup-homebrew@master
container: ghcr.io/homebrew/ubuntu22.04
# after
- uses: Homebrew/actions/setup-homebrew@<calver-tag-or-full-sha>
container: ghcr.io/homebrew/brew
Pick the tag from https://github.com/Homebrew/actions/releases. Scripts that clone Homebrew/brew should check out main, not master.
Symptom
Workflows using uses: Homebrew/actions/setup-homebrew@master (or any Homebrew/actions/*@master) fail to resolve, and jobs with container: ghcr.io/homebrew/ubuntu22.04 cannot pull the image.
Cause
Homebrew 7.0.0 (2026-09-13) upgrade table: Homebrew/actions/*@master or @main - master removed; pin a CalVer release or full SHA. ghcr.io/homebrew/ubuntu22.04 - image removed; migrate to ghcr.io/homebrew/brew. Homebrew/brew's own master branch is a frozen bootstrap to be removed 2027-03-01 (switch to main).
Verify
The workflow resolves the action and the container starts; brew --version prints 7.x.
