I've been pushing files to my project on GitHub for years without a problem, that was until this evening. Here's the error message:
ERROR: Repository not found fatal: The remote end hung up unexpectedly
Her e's how I fixed it, I was able to solve by opening .git/config and removing the [remote "origin"] section.
[remote "origin"] url = email@example.com:jrobertson/dynarex.git fetch = +refs/heads/*:refs/remotes/origin/*
then I ran the following (again)
git remote add origin firstname.lastname@example.org:jrobertson/dynarex.git git push -u origin master
