What you were trying to do (and why)

I'm trying to run brew cleanup to remove old cached bottles to free up some space.

What happened (include command output)

The old version of mongodb was not removed even though a new version is installed and running.

Command output

What you expected to happen

brew should remove old mongodb cache.

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

Installed old mongodb via brew command and it did update but cleanup failed to remove the new version. This has happened with me before with another formula and maybe it's not specific to mongodb.

Thanks, I'm experiencing the same issue.

I'm going to add my logs, hoping that they could be useful

$ brew install mongodb

To install 4.0.3_1, first run `brew unlink mongodb`

This is because we downgraded mongodb, see https://github.com/Homebrew/homebrew-core/pull/36078.

The last version in homebrew is 4.0.3_1 (4.0.5 should never have existed, it was a mistake).

I would recommend you to uninstall mongodb completely with brew uninstall mongodb, run brew cleanup to get rid of any caches, and then install it properly again.

Ah, got it. Now I remember, this happened once with node formula as well when a new version was released but then removed due to some dependency issue. The same situation took place then as well :smile:
