What you expected to happen

I expected brew to run without errors.

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

This morning when I ran brew update I received an error "Could could not read Username for 'https://github.com': terminal prompts disabled" and found this web page (https://jacopretorius.net/2018/05/git-error-could-not-read-username.html) & followed gitconfig instructions to enable SSH.

Now when I run brew update I get the error above. Explicit brew install and doctor commands work without issue.

I'm having the same problem.

From my investigation, it looks like these repositories were either moved, set private, or straight up deleted:

• https://github.com/Homebrew/homebrew-x11
• https://github.com/Homebrew/homebrew-boneyard
• https://github.com/Homebrew/homebrew-tex
• https://github.com/Homebrew/homebrew-fuse
• https://github.com/Homebrew/homebrew-binary

which is causing the problem to begin with.

my fix step:

~$ brew update
fatal: could not read Username for 'https://github.com': terminal prompts disabled
Error: Fetching /usr/local/Homebrew/Library/Taps/homebrew/homebrew-boneyard failed!

I had a different but probably related problem (that also broke my Homebrew): When I tried to update Homebrew it went into an infinite loop during which nothing seemed to happen.

When I now run brew update it says it's already up to date, except that it cannot find the command line tools (that are actually installed and that worked until the failed update). I tried reverting Homebrew to the previous version, and that fails too.

Running brew doctor gives two warnings:
"Xcode alone is not sufficient on Dunno." (because it can't find the command line tools)
and:
"Homebrew's sbin was not found in your PATH but you have installed formulae that put executables in /usr/local/sbin."
Executing the command given after the last warning does nothing.

Okay, editing my bash profile manually fixed the second error and replaced it by a new one (invalid macOS version).

Yes. That's because they were all empty and have been for at least a year and in most cases over two years. They were slowing down every brew update checking for updates to them.
