gem install codesake-dawn error

[dinosn]

Trying to install via gem install codesake-dawn -P MediumSecurity, I'm hitting this error,

gem install codesake-dawn -P MediumSecurity
Fetching: rainbow-2.0.0.gem (100%)
Fetching: net-http-digest_auth-1.4.gem (100%)
ERROR: While executing gem ... (RuntimeError)
Couldn't verify data signature: Untrusted Signing Chain Root: cert = '/CN=drbrain/DC=segment7/DC=net', error = 'path "/root/.gem/trust/cert-b3b79ed4cc5283914d3bd29871579372f9780cd4.pem" does not exist'

Looking for the certificate of CN=drbrain/DC=segment7/DC=net, I ended up on

https://raw.githubusercontent.com/bradleybuda/bundler_signature_check/master/certs/brad-meldium-public.pem

This is though a dummy certificate under '/CN=me/DC=example/DC=com'

Simply add that certificate, and retry. Please note that is not an issue directly related to dawn:

gem cert –add <(curl -Ls  https://raw.githubusercontent.com/bradleybuda/bundler_signature_check/master/certs/brad-meldium-public.pem)
