@vtolstov I'd fail fast - why bother moving forward if you cannot download cookbooks? The old code using `Chef::Mixin::Command.run_command` would raise `Chef::Exceptions::Exec` on error from the command resulting in interruption, see: https://gist.github.com/kwilczynski/40c2f3a68af69566b672. I recommend you try some of the code to see what it actually does, it's fun too!
