• Thinkpad T470
• Fedora 36
• ID 138a:0097 Validity Sensors, Inc.
• installed python-validity using copr

When I run fprintd-enroll I get the following error: Impossible to enroll: GDBus.Error:net.reactivated.Fprint.Error.NoSuchDevice:

sudo systemctl status python3-validity shows:

Please let me know what else I can try

I just ran into this issue with Fedora 36 on my T480 a few hours ago. Run sudo systemctl stop python3-validity then sudo dnf remove open-fprintd fprintd-clients fprintd-clients-pam python3-validity After that, I installed all those packages again (sudo dnf install open-fprintd fprintd-clients fprintd-clients-pam python3-validity) and rebooted, then followed the guide like normal. Then it worked fine and I didn't get the 0404 error anymore

Edit: Fixed last command to install

@IceCloud76 Dang, I was really hoping that would work for me. I see no change at all.

FYI running sudo validity-led-dance does indeed cause the fingerprint reader LED to blink. I feel like I am so close.

Same problem here with fedora 36 but running the 9a sensor on a thinkpad X280.

Nevermind I just followed #89 and the problem is fixed :)
