Marvel install failing

I've raised a similar question about Shield Install failing and suspect it's the same answer here.

When I run

bin/plugin -i elasticsearch/marvel/latest

to download the Marvel trial, it fails as cannot find the github package.

Can this be fixed and / or the documentation updated?

This can be ignored; it was my proxy getting in the way without telling me.

Just manually downloaded from http://download.elasticsearch.org/elasticsearch/marvel/marvel-latest.zip and it's fine.
