Can't install latest nightly on 2019-01-10

Installing rust nightly with rustup returns this error:

info: syncing channel updates for 'nightly-x86_64-unknown-linux-gnu'
info: latest update on 2019-01-10, rust version 1.33.0-nightly (6ecad3383 2019-01-09)
info: downloading component 'rustc'
error: failed to parse url: nightly/2019-01-10/rustc-nightly-x86_64-unknown-linux-gnu.tar.xz
info: caused by: relative URL without a base

We're aware of this and a fix is pending in rust-lang/rust#57484. Sorry for the trouble!

Also, this issue is a compiler infra one, and it's not related to rustup. Please discuss it in rust-lang/rust#57488. Thanks!
