gem install bundler error

[fz66]

My docker version is 17.05.0-ce, build 89658be docker-compose version 1.12.0, build b31ff33. So i tried upgrading it and it throws the error [ Could not find a valid gem 'bundler' (>= 0), here is why: Unable to download data from https://rubygems.org/ - SSL_connect returned=1 errno=0 state=SSLv3 read server certificate B: certificate verify failed (https://rubygems.org/specs.4.8.gz) ]

Even when i do sh ./docker-build.sh it throws the same error. kindly advise.

ERROR: The certificate of ‘rubygems.org’ is not trusted. ERROR: The certificate of ‘rubygems.org’ is not yet activated. The certificate has not yet been activated] Tried downloading a particular .pem file as suggested in some blogs but couldn't get it to work. Any help is appreciated.

@fz66 Try gem update --system and make sure that OpenSSL is at the last version.
