Not a problem to you. It is only a warning, and that is something that Google has to fix by upgrading their keys.

More information can be found here.

There has also been a bug filed. Feel free to star it to help push the bug along.

It's not a problem that interferes with anything; you can ignore that message.

See the following AskUbuntu questions about it for more information:
