All it takes is a quick glance at the URL in question to see that. It's very much a stock ISO of an old Ubuntu release.
The URL could have been: hxxp://sketchy-torrent-site.tld/wiki/FOIA-Hillary%20Clinton%20Does%20Trump.real-legit.torrent.html and have pointed to a torrent that was really a copy of some Transformers movie or whatever. URLs are only meaningful to humans and can be deceptive or -- pinky to lip -- more than meets the eye.
So, I don't see anything really extra chilling about this. It's not an official mirror that got dinged here, people. Sheeh; OP is dumb and this is not newsworthy.
