### Verification

- [X] My `brew doctor` output says `Your system is ready to brew.` and am still able to reproduce my issue.
- [X] I ran `brew update` and am still able to reproduce my issue.
- [X] I have resolved all warnings from `brew doctor` and that did not fix my problem.
- [X] I searched for recent similar issues at https://github.com/Homebrew/homebrew-core/issues?q=is%3Aissue and found no duplicates.

### What were you trying to do (and why)?

use `fakeroot` to build a debian package with `dpkg`

### What happened (include all command output)?

`fakeroot` 1.36.2 just hangs with no output on the command line

Removing `fakeroot` from the invocation allows `dpkg` to proceed, with the caveat that uid/gid on the output is incorrect

Manually reverting to `fakeroot` 1.32 by copying the old formula from github resolves the hang.

### What did you expect to happen?

`fakeroot dpkg` command does not hang

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

```shell
brew install fakeroot dpkg
fakeroot dpkg

Manually reverting to fakeroot 1.32 by copying the old formula from github resolves the hang.

This makes it seem like an upstream issue. Have you reported this upstream?

[huguesb]

I must admit to having a hard time navigating upstream... Is the canonical repo on debian? launchpad? somewhere else?

This looks related to https://bugs.launchpad.net/ubuntu/+source/fakeroot/+bug/2068702 although that specific issue was supposedly fixed in 1.35.1 ( https://salsa.debian.org/clint/fakeroot/-/merge_requests/30 )

Is there a simple mechanism in homebrew to revert to known-good older releases when newer ones are knwon-broken (that doesn't require the kind of manual extraction of an old formula from git...) ?
