What you were trying to do (and why)

After running brew cleanup, I expected older versions to be cleared, which, for the most part, they were - with the exception of MongoDB, which has been installed and managed with HomeBrew. Likely an issue related to #35996 on brew-core

What happened (include command output)

So in short, brew cleanup doesn't appropriately recognise which version of MongoDB is installed - and which is the latest version.

Command output

    Warning: Skipping mongodb: most recent version 4.0.3_1 not installed

but running mongod --verson and brew upgrade mongodb shows a later version installed!

    db version v4.0.4

    git version: f288a3bdf201007f3693c58e140056adf8b04839

    allocator: system

    modules: none

    build environment:

        distarch: x86_64

        target_arch: x86_64

  

What you expected to happen

I'd expect the Homebrew package to recognise that in this instance 4 > 3, so should not skip MongoDB legacy packages in the cleanup process.

Step-by-step reproduction instructions (by running brew commands)

brew upgrade mongodb
brew cleanup

Again - likely linked to #35996 on brew-core.

We're not shipping the latest version of MongoDB as it's not under an open source license. You can fix this with brew uninstall --force mongodb; brew install mongodb.

Aha! That makes sense. Apologies that didn't occur to me to check. Will keep an eye out for this sort of thing in future before raising issues. Thanks!

@wotarpelo No worries, it's a bit of a confusing (hopefully) one-off.
