I see the problem more clearly now. I think this is a problem with the Rust installer no longer updating nightlies.

In [https://travis-ci.org/hyperium/h2/jobs/546966455#L446](https://travis-ci.org/hyperium/h2/jobs/546966455#L446) and [https://travis-ci.org/hyperium/h2/jobs/551001348#L450](https://travis-ci.org/hyperium/h2/jobs/551001348#L450), you see that the installer recognizes the existing nightly installation, but still updates it.

However, the next one [https://travis-ci.org/hyperium/h2/jobs/551930277#L448](https://travis-ci.org/hyperium/h2/jobs/551930277#L448) no longer does.

This seems to be a problem with [rustup.rs](https://github.com/rust-lang/rustup.rs).

I’ve reported the problem at
