Description

Hello actions / checkout team 👋

We have a report of actions checkout@v2 failing in an actions enabled beta on GHES 2.22 with the following message:

failed, reason: self signed certificate in certificate chain

This is running a simple workflow which only runs actions checkout and a one line hello world script.

Thanks!

Start by reproducing the simple workflow with actions/checkout@v2 on GHES 2.22 Actions beta and investigate the reported self-signed certificate error. Done means checkout completes successfully without the certificate-chain failure in that environment.
