joy is wasting 2+ hours troubleshooting login issues on your jenkins server, only to discover the github enterprise server your school runs, which you're using as an auth source, is no longer returning the cert chain with its ssl cert.
and then trying to troubleshoot why update-ca-certificates isn't adding the cert you just put in place to the java keystore.
and then just saying fuck it and adding it manually so you can get back to what you were supposed to be doing to begin with.
