I'm trying to install fingerprint-gui on my Lenovo Ideapad 520 having Ubuntu 20.04 on which fingerprint isn't working for now.
I tried going directly to Settings → Users → Automatic login and enabled the fingerprint login, but the error is:
Could not access any fingerprint readers Please contact your system administrator for help!
I also tried to install Fingerprint GUI:
sudo apt-add-repository ppa:fingerprint/fingerprint-gui && sudo apt-get update sudo apt-get install libbsapi policykit-1-fingerprint-gui fingerprint-gui
but encountered this error:
E: Package 'policykit-1-fingerprint-gui' has no installation candidate E: Package 'fingerprint-gui' has no installation candidate
What could be the problem here?
