Verification

• I ran brew update and am still able to reproduce my issue.
• I have resolved all warnings from brew doctor and that did not fix my problem.

What were you trying to do (and why)?

install brew

@Richards-MacBook-Air ~ % /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

What happened (include all command output)?

That's because you didn't read the issue form which told you to post this elsewhere.

There's an issue with your internet connection to GitHub. Homebrew cannot do anything about this.

Where is elsewhere? If it's a GH issue, then there should be mirrors for the artifacts.

Where is elsewhere?

The install repository. Don't create an issue there, though, because it'll be closed.

If it's a GH issue, then there should be mirrors for the artifacts.

If you're willing to work on this: awesome. This isn't something we have capacity to do.

This was fixed by runninguninstall, then retrying reinstall.

Something like:
$ /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/uninstall.sh)"

Quick scripts or common troubleshooting should be added to https://docs.brew.sh/ somewhere.
I found the solution in an issue on brew GH issues where someone replied to their own question with this solution.
