Cocoapods: Failed to Connect to Github to Update the Cocoapods/Specs Specs Repo

Updating Pod is not Working

Finally I found solution from satoshi-iwaki.

This error occurs because

GitHub invalidated vulnerable SSL / TSL on 2018/23.

1. Install (or update) Homebrew.

$ /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

$ brew update

2. Install (or update) OpenSSL.

$ brew install openssl

$ brew upgrade openssl

In the log at the time of installation openssl because the path of the output, in the street PATH wo .bash_profileso as to set in.

If you need to have this software first in your PATH run:

echo 'export PATH="/usr/local/opt/openssl/bin:$PATH"' >> ~/.bash_profile

$ source ~/.bash_profile

3. Check the version.

$ which openssl

/usr/local/opt/openssl/bin/openssl

$ openssl version

OpenSSL 1.0.2n 7 Dec 2017

4. Make sure you can access with TLSv 1.2.

$ openssl s_client -connect api.github.com:443

gives log like this.

5.Installing Ruby

Since I want to install Ruby separately from Ruby on the system, I install it so that it can be switched rbenv.

$ brew install rbenv ruby-build 

$ echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bash_profile 

$ echo 'if which rbenv > /dev/null; then eval "$(rbenv init -)"; fi' >> ~/.bash_profile

$ source ~/.bash_profile

6.Check the version of Ruby to install.

$ rbenv install --list

gives list of Available versions.

Install Ruby.

$ rbenv install 2.1.0

Switch the version.

$ rbenv global 2.1.0

7. Install CocoaPods.

$ gem install cocoapods -n /usr/local/bin

If you want to check pods version

$ pod --version

Confirm that pod update ends normally.

$ pod update

`pod repo update` does not happen error in CocoaPods

You might have a broken Specs repository. Cocoapods suggest you delete your local copies and reclone. Try:

$ sudo rm -fr ~/.cocoapods/repos/master

And then:

$ pod setup

I'd also recommend running:

sudo rm -fr ~/Library/Caches/CocoaPods/

before you run pod setup to clear the cache.

Unable to install pods using a legacy Cocoapods version

As iHulk states in his comment:

Use source "https://github.com/CocoaPods/Old-Specs" at top of your pod file

Pod install is staying on Setting up CocoaPods Master repo

You could try running in verbose mode:

pod install --verbose

That'll show you what cocoa pods are up to:

Setting up CocoaPods master repo

Cloning spec repo `master` from `https://github.com/CocoaPods/Specs.git` (branch `master`)
  $ /usr/bin/git clone 'https://github.com/CocoaPods/Specs.git' master
  Cloning into 'master'...

(as suggested here)

For me the above step took quite a long time as the repo (Dec 2016) is now 1.1 GB

Your project does not explicitly specify the CocoaPods master specs repo warning when running pod install

Run the command pod repo remove master
