When I click to Register or Sign In using Gerrit Code Review, I get this error: `Provider is not supported, or was incorrectly entered.`

And when I enter the URL into the OpenID field manually, it takes me to a Google page stating: `The page you requested is invalid.`

Any clue what's happening here?

**EDIT**: Upon further investigation, I realized that if I change the provided URL in the OpenID field to `http` rather than `https`, it will redirect me to Google properly and ask me to approve. However, on the redirect back to Gerrit, nothing seems to have happened. I tried registering/signing in multiple times and to no effect.

I've also looked in the `MySQL` database to see if any data was being stored, and there doesn't appear to be.

**EDIT 2**: I've now submitted [a bug report to Gerrit](http://code.google.com/p/gerrit/issues/detail?id=728).

**EDIT 3**: [Answered.](https://stackoverflow.com/questions/3705656/openid-with-gerrit-not-working/3706615#3706615) I'd have done well to read the previous bug reports a bit more closely. My sysadmin fu is also severely lacking. Nonetheless, this is solved as a duplicate of another bug and is a Debian issue; [see below](https://stackoverflow.com/questions/3705656/openid-with-gerrit-not-working/3706615#3706615).
