Missing module recorders.video_capture

[ng2303]

Whenever howdy tries to run I get this error. Test is working btw.

traceback (most recent call last): File "/lib/security/howdy/compare.py", line 23, in from recorders.video_capture import VideoCapture ModuleNotFoundError: No module named 'recorders.video_capture' Unknown error: 1

I searched and didn't find any similar issues. What should I do? After this happens when I try to use sudo I'm prompted to just enter my password.

I'm running Pop OS on a Dell XPS 13 if that helps.

It stopped doing that and is now giving me this error - [ WARN:0] global ../modules/videoio/src/cap_gstreamer.cpp (1758) handleMessage OpenCV | GStreamer warning: Embedded video playback halted; module source reported: Could not read from resource.

I am running 2.6.1, the latest release, as well, since similar documentations of this issue being fixed were for previous versions.

Running Debian Unstable, having the same issue with howdy 2.6.1 and 2.6.0, had not with 2.5.1. I think this might a dependency issue, tried to install python3-opengl manually but does not help

Running Ubuntu 20.10 with KDE Plasma. Lock screen fails, but sudo and other prompts work.

I managed to debug the issue by running: /usr/lib/x86_64-linux-gnu/libexec/kscreenlocker_greet --testing

The output is:

Hope this helps in the debug process.

I experienced a similar issue on my Dell XPS 9500 running popOS 20.10. After digging around I noticed that folder /lib/security/howdy/recorders did not have the right permissions. Changing them with sudo chmod a+x /lib/security/howdy/recorders solved the problem for me.

:+1: solved by @bartp1990 's solution. thank you so much :)

I got on Debian Unstable after re-upgrading from howdy 2.5.1 to 2.6.1 another issue:

Traceback (most recent call last):
  File "/lib/security/howdy/compare.py", line 283, in <module>
    make_snapshot("SUCCESSFUL")
  File "/lib/security/howdy/compare.py", line 55, in make_snapshot
    snapshot.generate(snapframes, [
  File "/usr/lib/security/howdy/snapshot.py", line 54, in generate
    os.makedirs(abpath + "/snapshots")
  File "/usr/lib/python3.8/os.py", line 223, in makedirs
    mkdir(name, mode)
PermissionError: [Errno 13] Permission denied: '/usr/lib/security/howdy/snapshots'

Said directory does not exist and permissions of parent would only allow root to create a directory (stripped other dirs/files):

$ ls -la /usr/lib/security/howdy
drwxr-xr-x 8 root root 4096 18. Nov 18:04 .

after creating the directory manually (sudo mkdir /usr/lib/security/howdy/snapshots) everything works for me too. Thanks to @bartp1990

Note: /lib is symlinked to /usr/lib on my system.
