fprint- Device already claimed (Ubuntu 18.04/Thinkpad X230)

Solution 1:

I had this same problem just now, here's how I solved it:

  1. Open the system monitor(make sure to set your view to all processes.)
  2. Search for fprint/fprintd.
  3. End/Kill the fprint process.
  4. In a terminal run fprintd-verify.

That fixed it for me.

I think ending the process removed the previous claim on the scanner, allowing a new claim to be made.

Hope this helps, have a wonderful day!
