I can install packages but I can't update brew.

What's which -a git say?

Does this persist after running cd $(brew --repository) && git pull?

I figured it out.

I had GIT set to my personal git server in my bashrc. (To make git $GIT/repo a nice short command)

It looks like e942726 introduced GIT as a new env variable. I was able to update to that version, but was unable to update again. I removed my env var and everything was dandy.

Ahhhh... yeah, would've been nice to have a more useful warning about this. :) I just renamed my existing $GIT to $GIT_HOME, and all is well. Thanks!
