git clone on fresh machine fails

[jwbruce]

Installing tock and tock-teensy on a new machine. Issued the obligatory
git clone --recursive https://github.com/tock/tock-teensy.git
at the prompt.

It clones away until it crashes with

I was able to clone it recursively just now, and the error message looks like you were unable connect to GitHub to clone the Lua subrepository. Perhaps this was some sort of temporal network error. Try again maybe?

Nope. Just tried it.... 24 OCT 2018 15:37 EDT Same failure.

Hrm... well in any case, this error is saying your computer isn't able to connect to GitHub:

fatal: unable to connect to github.com:
github.com[0: 192.30.253.113]: errno=Connection refused
github.com[1: 192.30.253.112]: errno=Connection refused

Note that the URI used is git:// which is over port 9418. Perhaps that's somehow blocked by your firewall?

Also note that you don't actually need to clone the Lua repository unless you intend to build Lua-based apps, so you could just as easily clone the repo non-recursively, and just manually pull in the submodules you need.
