SSL_connect returned=1 errno=0 state=SSLv3 read server certificate B: certificate verify failed

I ran into a similar problem when trying to use the JQuery generator for Rails 3

I solved it like this:

1. Get the CURL Certificate Authority (CA) bundle. You can do this with:

   • sudo port install curl-ca-bundle [if you are using MacPorts]
   • or just pull it down directly wget http://curl.haxx.se/ca/cacert.pem

2. Execute the ruby code that is trying to verify the SSL certification: SSL_CERT_FILE=/opt/local/etc/certs/cacert.pem rails generate jquery:install. In your case, you want to either set this as an environment variable somewhere the server picks it up or add something like ENV['SSL_CERT_FILE'] = /path/to/your/new/cacert.pem in your environment.rb file.

You can also just install the CA files (I haven’t tried this) to the OS — there are lengthy instructions here — this should work in a similar fashion, but I have not tried this personally.

Basically, the issue you are hitting is that some web service is responding with a certificate signed against a CA that OpenSSL cannot verify.

If you’re using RVM on OS X, you probably need to run this:

rvm osx-ssl-certs update all

And here is the full explanation: https://github.com/wayneeseguin/rvm/blob/master/help/osx-ssl-certs.md

Update

On Ruby 2.2, you may have to reinstall Ruby from source to fix this. Here’s how (replace 2.2.3 with your Ruby version):

rvm reinstall 2.2.3 --disable-binary

Excerpt:

The Manual Way (Boring)

Download the cacert.pem file from http://curl.haxx.se/ca/cacert.pem. Save this file to C:RailsInstallercacert.pem.

Now make ruby aware of your certificate authority bundle by setting SSL_CERT_FILE. To set this in your current command prompt session, type:

set SSL_CERT_FILE=C:RailsInstallercacert.pem

To make this a permanent setting, add this in your control panel.

Ruby can’t find any root certificates to trust.

Take a look at this blog post for a solution: “Ruby 1.9 and the SSL error“.

The solution is to install the curl-ca-bundle port which contains the same root certificates used by Firefox:

sudo port install curl-ca-bundle

and tell your https object to use it:

https.ca_file="/opt/local/share/curl/curl-ca-bundle.crt"

Note that if you want your code to run on Ubuntu, you need to set the ca_path attribute instead, with the default certificates location /etc/ssl/certs.

The reason that you get this error on OSX is the rvm-installed ruby.

If you run into this issue on OSX you can find a really broad explanation of it in this blog post:

http://toadle.me/2015/04/16/fixing-failing-ssl-verification-with-rvm.html

The short version is that, for some versions of Ruby, RVM downloads pre-compiled binaries, which look for certificates in the wrong location. By forcing RVM to download the source and compile on your own machine, you ensure that the configuration for the certificate location is correct.

The command to do this is:

rvm install 2.2.0 --disable-binary

if you already have the version in question, you can re-install it with:

rvm reinstall 2.2.0 --disable-binary

(obviously, substitute your ruby version as needed).

The issue is that ruby can not find a root certificate to trust. As of 1.9 ruby checks this. You will need to make sure that you have the curl certificate on your system in the form of a pem file. You will also need to make sure that the certificate is in the location that ruby expects it to be. You can get this certificate at…

http://curl.haxx.se/ca/cacert.pem

If your a RVM and OSX user then your certificate file location will vary based on what version of ruby your using. Setting the path explicitly with :ca_path is a BAD idea as your code will not be portable when it gets to production. There for you want to provide ruby with a certificate in the default location(and assume your dev ops guys know what they are doing). You can use dtruss to work out where the system is looking for the certificate file.

In my case the system was looking for the cert file in

/Users/stewart.matheson/.rvm/usr/ssl/cert.pem

however MACOSX system would expect a certificate in

/System/Library/OpenSSL/cert.pem

I copied the downloaded cert to this path and it worked. HTH

The new certified gem is designed to fix this:

https://github.com/stevegraham/certified

Just add gem ‘certified’ in your gemfile and run bundle install.

1. gem ‘certified‘
2. bundle install

On Mac OS X Lion with the latest macport:

sudo port install curl-ca-bundle  
export SSL_CERT_FILE=/opt/local/share/curl/curl-ca-bundle.crt  

Then, rerun the failed job.

Note, the cert file location seems to have changed since Eric G answered on May 12.

A one liner fixes it for Windows in an Admin prompt

choco install wget (first see chocolatey.org)

wget http://curl.haxx.se/ca/cacert.pem -O C:cacert.pem && setx /M SSL_CERT_FILE "C:cacert.pem"

Or just do this:

gem sources -r https://rubygems.org/
gem sources -a http://rubygems.org/

Milanio’s method:

gem sources -r https://rubygems.org
gem sources -a http://rubygems.org 
gem update --system
gem sources -r http://rubygems.org
gem sources -a https://rubygems.org

gem install [NAME_OF_GEM]

Well this worked for me

rvm pkg install openssl
rvm reinstall 1.9.2 --with-openssl-dir=$rvm_path/usr

Something is wrong with openssl implementation of my ubuntu 12.04

Here’s another option for debugging purposes.

Be sure never to use this in any production environment, as it will negate benefits of using SSL in the first place. It is only ever valid to do this in your local development environment.

require 'openssl'
OpenSSL::SSL::VERIFY_PEER = OpenSSL::SSL::VERIFY_NONE

While knowing it’s rather a lame solution, I’m still sharing this because it seems like very few people answering here use Windows, and I think some of Windows users (me included) would appreciate a simple and intuitive approach.

require 'openssl'
puts OpenSSL::X509::DEFAULT_CERT_FILE

That tells where your openssl is looking for the cert file. My name is not Luis, but mine was C:/Users/Luis/Code/luislavena/knap-build/var/knapsack/software/x86-windows/openssl/1.0.0l/ssl/cert.pem. The path may be different depending on each own environments (e.g. openknapsack instead of luislavena).

The path didn’t change even after set SSL_CERT_FILE=C:foobarbazcert.pem via the console, so… I created the directory C:UsersLuisCodeluislavenaknap-buildvarknapsacksoftwarex86-windowsopenssl1.0.0lssl in my local disk and put a cert file into it.

Lame as it is, this will surely work.

I’ve try install curl-ca-bundle with brew, but the package is no available more:

$ brew install curl-ca-bundle
Error: No available formula for curl-ca-bundle 
Searching formulae...
Searching taps...

The solution that worked to me on Mac was:

 $ cd /usr/local/etc/openssl/certs/
 $ sudo curl -O http://curl.haxx.se/ca/cacert.pem

Add this line in your ~/.bash_profile (or ~/.zshrc for zsh):

export SSL_CERT_FILE=/usr/local/etc/openssl/certs/cacert.pem

Then update your terminal:

$ source ~/.bash_profile

I had this same issue while working on a Ruby project. I am using Windows 7 64bit.

I resolved this by:

1. Downloading the cacert.pem file from http://curl.haxx.se/ca/cacert.pem.
2. Saved that file to C:/RubyCertificates/cacert.pem
3. Then set my environmental variable “SSL_CERT_FILE” to “C:RubyCertificatescacert.pem”

source: https://gist.github.com/fnichol/867550

The most straightforward answer which worked for me was this

sudo apt-get install openssl ca-certificates

And voila!!!

OS X 10.8.x with Homebrew:

brew install curl-ca-bundle
brew list curl-ca-bundle
cp /usr/local/Cellar/curl-ca-bundle/1.87/share/ca-bundle.crt /usr/local/etc/openssl/cert.pem

Then, as this blog post suggests,

“How to Cure Net::HTTP’s Risky Default HTTPS Behavior“

you might want to install the always_verify_ssl_certificates gem that allow you to set a default value for ca_file.

This worked for me. If you using rvm and brew:

rvm remove 1.9.3
brew install openssl
rvm install 1.9.3 --with-openssl-dir=`brew --prefix openssl`

I ran into this issue and the suggested fix of rvm osx-ssl-certs update all did not work despite that I am an RVM user on OSX.

The fix that worked for me was re-installing the latest version of openssl:

brew update
brew remove openssl
brew install openssl

I fixed this problem by running this in terminal. Full writeup is available over here

rvm install 2.2.0 --disable-binary

OSX solution:

install latest rvm stable version

rvm get stable

use rvm command to solve the certificates automatically

rvm osx-ssl-certs update all

If you are running your rails app locally then just add this line at the bottom of application.rb.

OpenSSL::SSL::VERIFY_PEER = OpenSSL::SSL::VERIFY_NONE

After this you can use the app without any issues. You may call it a hack but it is not recommended. Use only when you need to run locally

Here’s what I did that helped if you are specifically having a problem on Leopard.

My cert was old and needed to be updated. I downloaded this:

http://curl.haxx.se/ca/cacert.pem

Then replaced my cert which was found here on Leopard:

/usr/share/curl/curl-ca-bundle.crt

Reload whatever you have that’s accessing it and you should be good to go!

Just because instructions were a slight bit different for what worked for me, I thought I add my 2 cents:

I’m on OS X Lion and using macports and rvm

I installed curl-ca-bundle:

sudo port install curl-ca-bundle

Then I adjusted my omniauth config to be this:

Rails.application.config.middleware.use OmniAuth::Builder do
  provider :google_oauth2, APP_CONFIG['CONSUMER_KEY'], APP_CONFIG['CONSUMER_SECRET'],
           :scope => 'https://www.google.com/m8/feeds https://www.googleapis.com/auth/userinfo.profile',
           :ssl => {:ca_path => "/share/curl/curl-ca-bundle.crt"}
end

If you have a symbolic link in the /usr/local/etc/openssl pointing to cert.pem try to do this:

ruby -ropenssl -e "p OpenSSL::X509::DEFAULT_CERT_FILE" (should be /usr/local/etc/openssl)
cd /usr/local/etc/openssl
wget http://curl.haxx.se/ca/cacert.pem
ln -s cacert.pem 77ee3751.0 (77ee3751.0 is my symbolic link, should depend on the openssl version)

What worked for me is a combination of answers, namely:

# Reinstall OpenSSL
brew update
brew remove openssl
brew install openssl
# Download CURL CA bundle
cd /usr/local/etc/openssl/certs
wget http://curl.haxx.se/ca/cacert.pem
/usr/local/opt/openssl/bin/c_rehash
# Reinstall Ruby from source
rvm reinstall 2.2.3 --disable-binary

I had trouble for a number of days and was hacking around. This link proved out to be extremely helpful for me. It helped me to do a successful upgrade of the SSL on MAC OS X 9.

Sometime it’s not always rvm’s problem
in MAC OSX,if you remove .rvm,the problem still(espcially while you backup data from timemachine) ,you can try this way.

1.brew update
2.brew install openssl

Adding gem 'certified', '~> 1.0' to my Gemfile and running bundle solved this issue for me.
