Cargo nightly cargo 0.16.0-nightly (3568be9 2016-11-26) fails to update the registry when running cargo update.
After trying ~10 times, I ran rustup run stable cargo update and it worked(on stable).

Here is the log on another Rust application:

Thanks for the report! I believe this is #3340 which is now being tracked for rustup at rust-lang/rustup#844
