fprintd failing after opencv upgrade

fprintd service fails to start due to opencv upgrade:

Aug 08 10:53:54 khruang fprintd[27511]: /usr/lib/fprintd: error while loading shared libraries: libopencv_features2d.so.413: cannot open shared object file: No such file or directory

[root@khruang ~]# ldd /usr/lib/fprintd  | grep opencv
        libopencv_features2d.so.413 => not found
        libopencv_core.so.413 => not found

[root@khruang ~]# pacman -Ql opencv | grep -E 'libopencv_(core|features2d)'
opencv /usr/lib/libopencv_core.so
opencv /usr/lib/libopencv_core.so.5.0.0
opencv /usr/lib/libopencv_core.so.500

Any way to get it working other than downgrading opencv?

look at the package content and links to so names, maybe they updated the file structure,  libopencv_features2d.so.413 doesn't exist anymore, so maybe you can try restart your system if you didn't try that yet.

Re: fprintd failing after opencv upgrade

you are using an unofficial and unsupported libfprint package, so you should ask wherever you got that from.
