Clicking throught the "Details", I see following errors in nightly:

$ rustup component add rustfmt-preview

error: component 'rustfmt' for target 'x86_64-unknown-linux-gnu' is unavailable for download for channel 'nightly'

If you require these components, please install and use the latest successful build version,

which you can find at <https://rust-lang.github.io/rustup-components-history>.

After determining the correct date, install it with a command such as:

    rustup toolchain install nightly-2018-12-27

Then you can use the toolchain with commands such as:

    cargo +nightly-2018-12-27 build

The command "rustup component add rustfmt-preview" failed and exited with 1 during .

It seems likely an env issue on CI?
