Chrome Version: 71.0.3578.98
OS: Ubuntu 18.04

What steps will reproduce the problem?
(1) Enable 2FA for Google and register a Titan key on another computer
(2) Try to login using Chrome on a freshly installed Ubuntu 18.04

What is the expected result?
Security key is not found. Chrome realizes this is Ubuntu and probably mis-configured. Show a message pointing to a support page which suggests doing the same thing the Yubico support page does: https://support.yubico.com/support/solutions/articles/15000006449-using-your-u2f-yubikey-with-linux

What happens instead?
Security key is not found. Chrome gives no helpful feedback other than suggesting to retry.
