Comment 9 for bug 1917178

I was able to get it back up and running.
First, make sure that you re-enable the repositories and sources for open-fprintd(groovy for now as there is no package for hirsuite).
Then use apt to install open-fprintd, fprintd-clients and python3-validity.
This should remove fprintd and libpam-fprintd. After that is done you should be able to see the login using fingerprint in ubuntu settings->Users.
To get it working with sudo I just had to rerun sudo pam-auth-update and re-enable fingerprint.
