Output of brew doctor

Warning: Homebrew's "sbin" was not found in your PATH but you have installed
formulae that put executables in /usr/local/sbin.
Consider setting your PATH for example like so:
  fish_add_path /usr/local/sbin

Warning: Some installed formulae are missing dependencies.
You should `brew install` the missing dependencies:
  brew install python@3.13

Run `brew missing` for more details.

Description of issue

When I run brew install python@3.13, it seems to infinite loop and never finish installing.

Rerunning with --verbose, I get this output:

I've had the same problem I think. What I did:

brew uninstall --ignore-dependencies python@3.13

# Next line fixed things for me
rm -fr /home/linuxbrew/.linuxbrew/lib/python3.13

brew install --verbose python@3.13

[ferothefox]

Seeing this issue too. The fix for me was to manually link python using brew link and CTRL+C during the Pouring stage
