404 Not Found when adding PPA

**Describe the bug**
Attempting to add the guake PPA to Ubuntu 22.04. I have a feeling this is only a temporary outage but I decided to file a bug for two reasons. 1) There's something IPV6 going on with the IP address for the PPA and 2) I've used Ubuntu a long time and never seen this error before.
