Broken pipe and remote end hung up unexpectedly when pushing to GitHub

Broken pipe and remote end hung up unexpectedly when pushing to GitHub

Although I am using a wired connection, I recently got an error message when trying to git push a new project initially to a private GitHub repository:

$ Write failed: Broken pipe
$ fatal: The remote end hung up unexpectedly

Apparently, there were already some big files like PDFs, high resolution images and a database backup in the project.

Instead of picking out these huge files manually, this hint https://stackoverflow.com/a/54238315 was helpful, whatever magic that might be ^^:

$ git gc --aggressive --prune
