I cannot make pam invoke howdy as it did since the python 3.11 rebuild. Is anyone facing the same problem?

The bug of opencv is fixed now.

I am having the same issue as @Integral. Confirming that @husixu's fix worked for me. For those wondering, I downgraded vtk to 9.1.0 by running the following:

pacman -U /var/cache/pacman/pkg/vtk-9.1.0-26-x86_64.pkg.tar.zst

Integral commented on 2023-03-01 00:05 (UTC)

@husixu It works. Thank you :)

@Integral Seems like an opencv -> vtk dependency issue. I've downgraded vtk to 9.1.0 and that solves the issue for now.

I CANNOT use howdy now

Export this environment variable OPENCV_LOG_LEVEL=OFF to disable all OpenCV warnings.

@postblue Same warnings here. But as it works, I didn't look any further :-)

As part of a possible solution to make howdy work with python3 and delete python2 once and for all, I followed the links @imahaja suggested and wrote the PKGBUILD for the aforementioned fork pam-python-git. It's a fork not an upstream development, but since upstream's last push was on 2020-11-10 I think I safely assumed that castLabs's fork should work better in our situation.

If someone want to use @mika.cousin's patch, it's possible to edit the PKGBUILD directly and let makepkg handle it by itself by adding a patch file (here py3.patch):

With that all seems to work fine but now I have 3 lines of warnings each time I'm using the IR camera for authentication:

As anyone got the same and was able to fix this? I might be interested!

@iyanmv I was able to use howdy without python2:

  • Install pam-python-git which uses python3,

  • After, patch /lib/security/howdy/pam.py with
