Thank you for taking the time to report this bug and helping to make Ubuntu better. It sounds like some part of the system has crashed. To help us find the cause of the crash please follow these steps:
1. Look in /var/crash for crash files and if found run: ubuntu-bug YOURFILE.crash Then tell us the ID of the newly-created bug. 2. If step 1 failed then look at https://errors.ubuntu.com/user/ID where ID is the content of file /var/lib/whoopsie/whoopsie-id on the machine. Do you find any links to recent problems on that page? If so then please send the links to us. 3. If step 2 also failed then apply the workaround from bug 994921, reboot, reproduce the crash, and retry step 1. Please take care to avoid attaching .crash files to bugs as we are unable to process them as file attachments. It would also be a security risk for yourself. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-control-center in Ubuntu. https://bugs.launchpad.net/bugs/1878285 Title: gnome-control-center crashes on setting up fingerprint Status in gnome-control-center package in Ubuntu: Incomplete Bug description: When I try to setup my fingerprint in gnome-control-center, I first have to choose which finger I would use, and when I press the "next" button, it crashes : "Unable to access device "Validity VFS0050" GDBus.Error:org.freedesktop.DBus.Error.NoReply:Message recipient disconnected from message bus without replying".
