Arch Linux

Please post the exact command you're running and the exact output

`sudo systemctl start fprintd.service`

```
systemd[1]: Starting Fingerprint Authentication Daemon...
fprintd[1296]: /usr/lib/fprintd: error while loading shared libraries: libcrypto.so.1.1: cannot open shared object file: No such file or direct>
systemd[1]: fprintd.service: Main process exited, code=exited, status=127/n/a
systemd[1]: fprintd.service: Failed with result 'exit-code'.
systemd[1]: Failed to start Fingerprint Authentication Daemon.
```

Installing the package `openssl-1.1` fixes it for me.

What is the output of lddtree /usr/lib/fprintd (requires pax-utils)
This is the output on my system, it does not show any linkage to libcrypto

Thank you for the hint.
So it seems that it is needed by `libfprint-2.so.2`

```
$ pacman -F libfprint-2.so.2
extra/libfprint 1.94.5-1 (fprint)
usr/lib/libfprint-2.so.2

Ah, I think I found the reason.
https://aur.archlinux.org/packages/libfprint-vfs009x-git needs it.
I'll close this issue ticket.

Thank you!
