Hi all, as we just found out the git protocol does not work inside the university network. So replace the git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git url with https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git note that if you already cloned at home you can change it in the .git/config file in the linux directory as well.
