Description
Rustup seems unable to download files on my system:
$ ./rustup.sh -v --default-toolchain nightly
info: downloading installer
Welcome to Rust!
This will download and install the official compiler for the Rust programming
language, and its package manager, Cargo.
It will add the cargo, rustc, rustup and other commands to Cargo's bin
directory, located at:
/home/ajr/.cargo/bin
This path will then be added to your PATH environment variable by modifying the
profile file located at:
/home/ajr/.profile
You can uninstall at any time with rustup self uninstall and these changes will
be reverted.
Current installation options:
default host triple: x86_64-unknown-linux-gnu
default toolchain: nightly
modify PATH variable: yes
1) Proceed with installation (default)
2) Customize installation
3) Cancel installation

rustup: command failed: /tmp/tmp.1idI66A40j/rustup-init -v --default-toolchain nightly
However, I think the "Couldn't resolve host name" error is a red herring. I can download the file manually:
$ curl https://static.rust-lang.org/dist/channel-rust-nightly.toml.sha256 -o /home/ajr/.rustup/tmp/5ow4nv7ga952c6gd_file

And I can definitely resolve the hostname "static.rust-lang.org":
$ dig static.rust-lang.org

Research direction
Reproduce the failure using ./rustup.sh -v --default-toolchain nightly and inspect the download path that reports the DNS error. Compare it with the successful manual curl request for channel-rust-nightly.toml.sha256. Done means rustup can download the nightly channel file and proceed with installation in the reported environment.
