Description of issue

I cannot install a formula I created under my own github org from a Linux VM but well from macbook . What is then the issue ?

Note: The git cloned project (= tap repo) under the VM matches a old commit (1h old - ch007m/homebrew-idpbuilder@557a744) vs not on my mac - ch007m/homebrew-idpbuilder@57a98f2

If I check the commits within the repository cloned locally, then I can find the last commit !!

From How to Create and Maintain a Tap:

Tap formulae follow the same format as the core’s ones, and can be added under either the Formula subdirectory, the HomebrewFormula subdirectory or the repository’s root.

Your idpbuilder.rb formula is under the formula subdirectory, which fails a case-sensitive path search on pretty much every Linux filesystem. macOS filesystems in common use are all case-insensitive, so it works there.

Stupid error. Many thanks
