- probably you need BIOS update

- install libssl1.1 ( I have 1.1.1f-1ubuntu2.22)

- get deb (version 5.8.012.0 works for me) and install from : http://dell.archive.canonical.com/updates/pool/public/libf/libfprint-2-tod1-broadcom/ 

And settings > system > users shows new login method with fingerprint,

that's all
