Also just got this in 20.04, after 19.10 (fresh install a couple of months ago) requested upgrade. I added 'sudo add-apt-repository ppa:fingerprint/fingerprint-gui' but it said gui not 20.04 compatible, so added 'sudo add-apt-repository ppa:fingerprint/fprint' then went into 'Software & Updates' and disabled ppa:fingerprint-gui and refreshed - which got stuck at perhaps 100% complete (Refreshing software cache' with purple underline equidistant from each end) 'journalctl -b 0' file attached (edited to remove earlier & sensitive stuff).
