Description of issue

I maintain a custom homebrew tap at https://github.com/cryfs/homebrew-tap. To fix another issue, we had to change the build dependency from "conan" to "conan@1". See cryfs/homebrew-tap#15. The tap repository uses Github Actions with Homebrew/actions to test changes.

While the formula without that change passes CI, the formula with that change passes CI on macos but fails on linuxbrew with

  /home/linuxbrew/.linuxbrew/Homebrew/Library/Homebrew/vendor/bundle/ruby/2.6.0/bin/bundle clean
  Error: No available formula with the name "cmake".

Any idea what is causing this and how I could fix it? Or at least get more information about what's going on? I tried adding a brew install cmake command to the beginning of the CI job. That executed fine, installed cmake, but then later still failed with the same error message.

This is a known issue that's being tracked at Homebrew/brew#15049. As a workaround, please try adding this to your workflow:

env:
  HOMEBREW_NO_INSTALL_FROM_API: 1

See the linked issue for more details.

Thanks, that worked :)
