Cocoapods: Failed to connect to GitHub to update the CocoaPods/Specs specs repo

Question

When running pod repo update the following error is generated:

Updating spec repo `master`
[!] Failed to connect to GitHub to update the CocoaPo         


        

Answer 1

Just update cocoapods: sudo gem install cocoapods

Answer 2

• update ruby and cocoapods.
• check ruby version in the cocoapods env.

use

pod env

rbenv global x.x.x
ruby -v

change ruby version. If not working, watch this rbenv not changing ruby version

check ruby version in the cocoapods env. If not changed,

which pod

make sure your pod path is /usr/local/bin/pod,if not

export PATH=/usr/local/bin:$PATH

Answer 3

A another solution similar to Max's and Adem's in this thread is found in a CocoaPods issue:

brew install ruby
sudo gem install cocoapods

Verify that you're using the latest and correct Ruby with:

ruby --version
which ruby

Should be using /usr/local/bin/ruby

Reason: It turns out that Github updated to only support TLS 1.2 on Feb 22nd. Older versions of MacOS before High Sierra come preinstalled with Ruby 2.0. This version uses OpenSSL 0.9.8 which "will fail with servers supporting only TLS 1.2."

Updating to the latest Ruby (2.5) and latest CocoaPods (1.4) fixed this for me without having to do anything with openssl (Ruby updates openssl). This is a good solution if you don't want to update to High Sierra just yet.

Answer 4

A slightly simpler solution from Adem's that doesn't use rbenv:

brew install openssl
brew upgrade openssl
brew install ruby
brew link --overwrite ruby

Finally, make sure you don't have your PATH variable set to have /usr/local/bin after $PATH. Your PATH export in ~/.bash_profile should look similar to this:

export PATH=/usr/local/bin:$PATH

Answer 5

If someone has these issues on Circle CI I was struggling with this for a day almost.

In the end I think the best way is to use their provided solution to download from their servers.

curl https://cocoapods-specs.circleci.com/fetch-cocoapods-repo-from-s3.sh | bash -s cf

From this link you can see that one of the cocoapods core contributor says that it's fine: The CocoaPods repo cache is updated roughly every 30 mins, which is usually frequent enough to only miss the last 6 pushes to the Specs repo.

Answer 6

I did next in Terminal:

1. brew install openssl

   if you don't have home brew:

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

   and repeat p.1

2. export PATH="/usr/local/opt/openssl/bin:$PATH"

3. openssl version

   Output:OpenSSL 1.0.2n 7 Dec 2017

4. pod update
