To be quite honest, this was a terrible week of CTF'ing for me. My main focus this week was on studying for my SANS GASF exam (more on that later) so I didn't get to dedicate much time in playing. With that said, I was able to complete part 1 of 2, partially by dumb luck.
Challenge 6 (Nov. 9-16) The Elephant in the Room (25)

Your task is to find the specific error code that led to this failed dependency installation. [Flag is numeric]
