Short and sweet: I recently upgraded to MacOS Catalina and Xcode 12 which broke my cocoapods install. Attempting to repair resulted in a possible scenario warranting a complete OS (or Xcode?) reinstall. I cannot get rubygems to allow for any source provider. I'm hoping to avoid the full reinstall of either the OS or Xcode.
Long version: After upgrading to MacOS Catalina and Xcode 12, my cocoapods installation for a local project yielded
Pod failure for arm64 (ArcGIS):
ld: building for iOS Simulator, but linking in dylib built for iOS, file '/<removed>/Pods/ArcGIS-Runtime-SDK-iOS/ArcGIS.framework/ArcGIS' for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
Attempting to re-install cocoapods with gem install cocoapods yielded:
-bash: /usr/local/bin/pod: /System/Library/Frameworks/Ruby.framework/Versions/2.3/usr/bin/ruby: bad interpreter: No such file or directory
I tried with both user and root level permissions. This sent me to Facing issue - bad interpreter: No such file or directory when used pod update on MAC
From there, I ended up upgrading rubygems manually. Once upgraded to 3.1.4, I again attempted to install cocoapods:
02:56:46$ sudo gem install cocoapods
ERROR: Could not find a valid gem 'cocoapods' (>= 0), here is why:
Unable to download data from https://rubygems.org/ - no such name (https://rubygems.org/specs.4.8.gz)
which led med down the wrong path of "they're still using TLS 1/SSLv3", do the following at https://stackoverflow.com/a/51015358 and https://stackoverflow.com/a/19179835. After using my own openssl s_client -connect rubygems.org:443 test I determined the SSLv3/TLSv1 issue to have been addressed. Regardless, I forced an IPv4 entry for rubygems.org in my /etc/hosts settings and removed the https://rubygems.org/ source link to drop in the insecure http://rubygems.org/ to do the update. And here's the break: I cannot figure out how to force it to allow me to re-add the https://rubygems.org/ source or even the insecure http://rubygems.org/ source
See the below terminal output which shows I can fully access the specs.4.8.gz from rubygems.org (no networking issue) and cannot re-add the sources link:

I am baffled by the issue of
no such name (https://rubygems.org/specs.4.8.gz)
given my ability to pull it using curl with no issue. I have tried removing the IPv4 entry from my /etc/hosts location, disabled IPv6 in my wireless, enabled IPv6 in my wireless. I am simply unable to force rubygems to re-enable the https://rubygems.org/ source.

My final attempt to repair (so far) was to re-install the rubygems again.
rubygems-3.1.4 04:29:28$ ruby setup.rb
ERROR: While executing gem ... (Errno::EROFS)
Read-only file system @ rb_sysopen - /System/Library/Frameworks/Ruby.framework/Versions/2.6/usr/bin/gem

Password:

So now, I can't even re-install ruby gems, let alone re-add the rubygems.org sources.
