Error updating to 1.23

I can put this in Github if needed. But I'm reluctant to automatically go to there if there is a solution or a ticket isn't really needed.

I'm using MacOS and just tried rustup update

error: could not download file from '' to '/Users/username/.cargo/bin/rustup-init'
info: caused by: error during download
info: caused by: [18] Transferred a partial file (transfer closed with 482184 bytes remaining to read)

Also ran, rustc --version and got back:

rustc 1.23.0 (766bd11c8 2018-01-01)

So I'm not sure if everything is all good or what I should do if anything to fix the error?

Perhaps a network issue? Have you tried it multiple times?
