[chef] knife ec2 problem on windows: Unable to verify certificate

[Jeppe Nejsum Madsen < >]

Ohai,

We've been using our own version of the knife-ec2 plugin since some features were missing. We've just upgraded to the official version and this brings in excon 0.31 which results in the following error:


C:\chef>bundle exec knife ec2 server list
←[33m[fog][WARNING] Unable to load the 'unf' gem. Your AWS strings may not be properly encoded.←[0m
ERROR: Excon::Errors::SocketError: Unable to verify certificate, please set `Excon.defaults[:ssl_ca_path] = path_to_certs`, `ENV['SSL_CERT_DIR'] = path_to_certs`, `Excon.defaults[:ssl_ca_file] = path_to_file`, `ENV['SSL_CERT_FILE'] = path_to_file` or `Excon.defaults[:ssl_verify_peer] = false` (less secure).

We used to pin excon to 0.24, but the latest knife-ec2 requires 0.31. We're using chef 11.12.4.

Any hints (besides disabling verification which is not an option :-)
