Problems running on Ubuntu 23.04 (lunar)

[tante]

Ubuntu 23.04 comes with a new version of Python (default is 3.11) that makes howdy not run properly.

The first issue is line 10 in pam.py: import ConfigParser The module is now called configparser so howdy can't properly import it.

Then the python 'dlib' module was missing, I installed it via sudo pip install --break-system-packages dlib.

Doing a mitigation by changing that line to import configparser as ConfigParser makes howdy work in GDM for login but when using it in sudo creates a funky error:

Traceback (most recent call last):
  File "/lib/security/howdy/compare.py", line 23, in <module>
    from recorders.video_capture import VideoCapture

The strange thing is: If you add import recorders to the file there is no problem. Just importing that submodule fails and seemingly only while trying it via sudo.

---

Linux distribution (if applicable): Ubuntu 23.04

Howdy version (sudo howdy version): Howdy 2.6.1

After changing the configparser import I had a different issue:

ModuleNotFoundError: No module named 'dlib'

After installing dlib with sudo pip install --break-system-packages dlib everything is working now.

@ashkop You made my day. Howdy is working fine in my Kubuntu 23.04 now.

sudo apt install -y python3-opencv
sudo pip install --break-system-packages dlib
sudo howdy add

[ashkop]

@kimhongsu I'm glad that helped. Would still be nice if howdy can be fully updated to python 3.

Here's my ugly hack workaround that also works for fresh install of howdy on 23.04, just skip the "apt remove howdy" command. Doing this also fixes the error when authenticating sudo in the first comment.

sudo -i mv /usr/lib/python3.11/EXTERNALLY-MANAGED /usr/lib/python3.11/DISABLED-EXTERNALLY-MANAGED apt remove howdy pip3 install dlib apt install howdy nano /lib/security/howdy/pam.py # Change ConfigParser to configparser on 2 lines mv /usr/lib/python3.11/DISABLED-EXTERNALLY-MANAGED /usr/lib/python3.11/EXTERNALLY-MANAGED

[skjerns]

nano /lib/security/howdy/pam.py # Change ConfigParser to configparser on 2 lines

note: You also need to change it elsewhere, or just change the line to import configparser as ConfigParser

[boltgolt]

This is an annoying one, using --break-system-packages should help but it's really not the clean way to do it. Maybe a venv for Howdy would be better

[Arad-Afzali]

I've recently updated to Ubuntu 23.04 and Howdy is not working on the lock screen. I tried to reinstall it but it didn't work. I can still add new faces and Howdy seems to work fine in the terminal and gives me no errors.

[dingwen07]

--break-system-packages is not a good practice. Maybe howdy could use virtual environments to install this package.

I've got the exact same issue with a fresh install of Ubuntu 23.04 Linux 6.2.0-20-generic 64-bit. Wrapping howdy inside of it's own venv would be the optimal solution here and for isolating its install further from the host.

[MurzNN]

@nate3D Thanks for the solution, could you please share an example of how to do the "Wrapping howdy inside of it's own venv"?

[MurzNN]

I've found a solution to the ModuleNotFoundError: No module named 'ConfigParser' error, the fix is in the https://github.com/boltgolt/howdy/issues/799

[Rongronggg9]

To those who are not willing to use --break-system-packages:

sudo pip install -t /lib/security/howdy dlib

Tested on the beta branch, should work on master.

[kimhongsu]

@boltgolt Could you let us know how to wrap howdy up with venv? Or is it possible to wrap howdy up with docker?

[Spurlos]

To those who are not willing to use --break-system-packages:

sudo pip install -t /lib/security/howdy dlib

Tested on the beta branch, should work on master.

@boltgolt Perhaps this fix can be incorporated in release or at least beta?

Tried on ubuntu 23.10 Could install howdy after installing dlib like this, but could not run howdy.

I am also get the same problem on Ubuntu version 23.10.1

Howdy Installation Issue on Ubuntu 23.10.1

Problem:

I encountered an issue with Howdy installation on Ubuntu version 23.10.1. The provided solutions seemed to have complications.

Workaround:

I found a workaround that worked for me, even on a fresh install of Ubuntu 23.10.1. Skip the "apt remove howdy" command to avoid additional errors during sudo authentication.

1. Open a root shell:

   sudo -i
   
   

2. Move the EXTERNALLY-MANAGED directory:

     mv /usr/lib/python3.11/EXTERNALLY-MANAGED /usr/lib/python3.11/DISABLED-EXTERNALLY-MANAGED
   
   

3. Remove Howdy (skip if fresh install):

    apt remove howdy
   
   

4. Install dlib using pip3: pip3 install dlib

   If pip3 doesn't work, try pip install dlib. If that also fails, attempt: sudo pip install --break-system-packages dlib

5. Reinstall Howdy:

    apt install howdy
   
   

6. Edit pam.py to fix import error:

    nano /lib/security/howdy/pam.py
   
   

Change import ConfigParser to import configparser as ConfigParser you can find on lines 2 to 11.

9. Restore EXTERNALLY-MANAGED directory:

    mv /usr/lib/python3.11/DISABLED-EXTERNALLY-MANAGED /usr/lib/python3.11/EXTERNALLY-MANAGED 
   
   

This workaround should help resolve the installation issues in my case.

While adding face some time you will get device_path problem but i am solve it like this.

 # Should be set automatically by an installer if your distro has one
 # device_path = /dev/v4l/by-path/pci-0000:00:14.0-usb-0:6:1.2-video-index1 # default in my config comment it add new below like this
 device_path = /dev/video0

I also have a silution without breaking system packages. This solution depends on a dep package which is not released yet.
