SSL verification error at depth 0: unable to get local issuer certificate (20)

[elviserikvan]

I don't know anything about ruby and gems, the reason that installed it it's because it is necesary to install sass, but when i run this command

gem install sass

This shows up

ERROR:  SSL verification error at depth 0: unable to get local issuer certificate (20)

i have already tried this tutorial

http://guides.rubygems.org/ssl-certificate-update/#manual-solution-to-ssl-issue

but i didn't help, what's going on?

My environment settings are:

C:\> ruby -v
ruby 2.5.0p0 (2017-12-25 revision 61468) [i386-mingw32]

C:\> gem -v
2.7.3

Windows 7 32 bits

It sounds like your Ruby install might not be configured to know where your SSL certificates are. Can you try following the steps in this guide and report back with the results? http://bundler.io/v1.16/guides/rubygems_tls_ssl_troubleshooting_guide.html

[elviserikvan]

Ok, let's see.

The guide said that needed to run this command

 curl -sL https://git.io/vQhWq | ruby

to know whether my errors result from the SSL certs issue or the TLS versions issue. But i did't show anything, I run this command twice but in neither of them showed something. Just the prompt shows to write another command again.

I tried to update the bundler running this command

 gem install bundler

But the same error showed up

ERROR:  SSL verification error at depth 0: unable to get local issuer certificate (20)
ERROR:  You must add /C=EN/CN=e9be946d3338ec7a 2 to your local trusted store

ERROR:  You must add /C=EN/CN=e9be946d3338ec7a 2 to your local trusted store

Then I tried to update RubyGems. I downloaded the lastest .gem update that i could find, it was the 2.7.6, before that version i was using the 2.7.3, i don't know it would do a huge change, but i did it just because. Ok i updated to that version and then i checked it with gem -v and the right version was installed, but when i run the command to install sass the same error shows up again

Then the guide said to install new CA certificates, I did it (again) but i didn't help.

I don't know what's hapenning, i tried to reintall ruby with the ruby installer like three times... God

Honestly, I think that it isn't a RubyGems's issue, because i have MesaSync Installed and sometimes an error shows up saying something about the SSL certificates like this error, but i don't know why, and even is it isn't a RubyGems error I still need help, so please help me

[bronzdoc]

Sorry @GamertodArk this issue tracker is for Rubygems, if your problem is not related to Rubygems i must close this issue, we can't help you with MegaSync beacuse we don't know nothing about it.

[indirect]

@GamertodArk I am not sure if this will help you, but the error message definitely makes it seem like Ruby cannot find the CA certificates, even though you have installed them. You might be able to get more help troubleshooting by going to superuser.com and posting under the "windows" tag. Good luck figuring it out!

I have experienced the same issue on Windows 10 os (I am using a Web-Filter which proxies web requests via a Certificate Livigent CA):

C:\Users\SDP>gem install rake

, could it possibly be related to a bad/unrecognized certificate?

@SDP190

Have you tried running:
https://raw.githubusercontent.com/rubygems/ruby-ssl-check/master/check.rb

Or, can you connect with Ruby Net::HTTP using ssl?

I had this issue before, and solved it by upgrading rubygems-update from 2.6.12 to 2.7.11.

[ashish91]

I was facing the issue due to .gemrc:

---
:update_sources: true
:sources:
- https://gems.rubyforge.org/
- https://gems.github.com
:benchmark: false
:bulk_threshold: 1000
:backtrace: false
:verbose: true
gem: --no-ri --no-rdoc

[hsbt]

- https://gems.rubyforge.org/
- https://gems.github.com

Above sources have been retired. You don't need to use :sources: section if you use only https://rubygems.org.

Closing since this was answered.
