@prafullakota,
We do encounter fprintd-verify is not working on 20.04 and a bug is here. Not sure if you can access it. Bug #1940619

Below is the debug info by KC.

On the passed device XPS 13 (Modena TGL). The fprintd will emit VerifyFingerSelected at once when the test started. Then the application fprintd-verify will ready to receive VerifyStatus(verify-no-match) event.

On Broadcom's fingerprint, it will not get the VerifyFingerSelected immediately, then the fprintd-verify application keeps waiting. Once the user touch the fingerprint sensor it will receive two signal 1. VerifyStatus(verify-no-match) 2. VerifyFingerSelected. Then the fprintd-verify put itself info ready to verification phase, however, the VerifyStatus(verify-no-match) signal has emitted already, so it will wait eternally.
