Successfully installed asdf install ruby 2.6.6 following this post on my fresh MacBook Pro M1 2021, and trying to run gem install bundler, but getting this:

MacBook-Pro ~ % gem install bundler

I tried to open Mac's Keychain Access window and specify Always Trust option for every GlobalSign certificate, but no luck.

I also followed that guide, and ran into this issue. Try this: check directory /opt/homebrew/etc see if you have openssl@1.1 if not, you probably need to reinstall using brew reinstall openssl@1.1. openssl1.1 is what i use for ruby 2.6.5, you might need to check that for your ruby version.

Also, i am not entirely sure about this, but I also added a couple more env variables to the ~/zshrc file following this guide. Be sure you are changing the "openssl@1.0" to "openssl@1.1" or whatever your ruby version uses.
