Brew update failed: untracked working tree files would be overwritten by merge

Question

Trying to update Homebrew with brew update I got the following error

error: The following untracked working tree files would be overwrittenby me         


        

Answer 1

I had a similar issue where my brew package library got downloaded as a root user and then I was not able to run brew update as git would complain about not able to merge the file.

Solution was to do :-

sudo chown -R  /usr/local/Library
