Description

If we try to install python@3.10 or python@3.11 via a formula, dependency or manually via brew after running brew update the sym linking fails, which causes the install to fail. We came across this issue when testing the homebrew formulae for apache/arrow.

Is it regression?

Yes, we have been running these builds for years at this point but I was unable to pinpoint the exact date were the failures begun (due to log limits)

Expected behavior

python 3.11/3.10 is installed and sym linked by brew (or detected as installed)

Actual behavior

Error: The `brew link` step did not complete successfully
The formula built, but is not symlinked into /usr/local
Could not symlink bin/2to3-3.11
Target /usr/local/bin/2to3-3.11
already exists. You may want to remove it:
  rm '/usr/local/bin/2to3-3.11'

Repro steps

1. brew update to detect the broken linkage
2. brew install python@3.11
