@Mina this solution didn't help https://askubuntu.com/a/924475/174392. I've just installed a lot of garbage in my system expecting it to work. There was no 'fprint-demo_0.4-1_amd64.deb' file. '/etc/init.d/vcsFPServiceDaemon' is a text file in my case (if it matters) and finished with this message:
/etc/init.d/vcsFPServiceDaemon: 33: .: Can't open /etc/rc.status
and 'sudo: fprint_demo: command not found'.
