Problem updating brew on Mac

After trying to update brew on my Mac today I have run into this error:

ggarron$ brew update
error: SSL certificate problem: Invalid certificate chain while accessing https://github.com/Homebrew/homebrew.git/info/refs?service=git-upload-pack
fatal: HTTP request failed
Error: Failure while executing: git pull -q origin refs/heads/master:refs/remotes/origin/master

After doing some research I have found that the problem was an Expired Certificate from DigiCert

The way to solve the problem is explained here

After removing all expired certificates I got this ones.

Keychain Access Mac

In case you are missing one of them, you can download from this webpage: DigiCert Certificates.

Just choose one of them, copy the url by righ-clicking on the Download link and selecting Copy link location, then go to your terminal and download it.

curl -O [the link goes here]

You then have to double click on the file using finder, it will ask for our password and the certificate will be installed.

You should now be able to run:

brew update
