Fixed policyd-rate-limit: Uses deprecated yaml.load error on Debian 12

When updating or installing PolicyD on Debian 12, it is possible to encounter an error related to the use of the deprecated yaml.load function. This error might be in the form of “policyd-rate-limit: Uses deprecated yaml.load”. Fortunately, there is a simple solution to remedy this situation.

This step-by-step guide will show you how to resolve this error and update PolicyD successfully.

Step 1: Console Access or SSH

Make sure that you are logged in to your Debian 12 system via the console or SSH as a user with administrative privileges (root or a user with sudo).

Step 2: Open the affected file

Use the Nano text editor to open the file utils.py where the deprecated yaml.load reference is located.

sudo nano /usr/lib/python3/dist-packages/policyd_rate_limit/utils.py 

Step 3: Replace yaml.load

Check the file for code that uses yaml.load. You’ll probably find it in a section that loads YAML settings or configurations. Change this line to yaml.full_load.

Before modification:

self._config = yaml.load(f) 

After modification:

self._config = yaml.full_load(f) 

After making this change, save the file using the Nano-specific commands (Ctrl + O to save, then Ctrl + X to exit).

Step 4: Restart PolicyD

For the changes to take effect, restart the PolicyD service. You can do this by using the following command:

sudo systemctl restart policyd 

Step 5: Verification

Once the reboot is complete, check to see if the error has been resolved. You can do this by checking the system logs or by running the command that caused the initial error again.

Bonus: Command Line Editing with SED

sudo sed -i 's/yaml\.load/yaml\.full_load/g' /usr/lib/python3/dist-packages/policyd_rate_limit/utils.py
  • sudo: runs the command as an administrator, because we need to modify a system file.
  • sed: The command-line tool for performing text substitutions.
  • -i: Instructs sed to modify the file in place.
  • s/yaml\.load/yaml\.full_load/g‘: This is the substitution expression. It looks for all occurrences of yaml.load and replaces them with yaml.full_load. The g at the end means that this is done globally, i.e. for all occurrences on each line.
  • /usr/lib/python3/dist-packages/policyd_rate_limit/utils.py: the path to the utils.py file of PolicyD where we want to make this substitution.

By following these steps, you should have resolved the PolicyD Update Python error on your Debian 12 system. Be sure to verify that PolicyD is working properly after the update. If you encounter any other issues or errors, refer to the official PolicyD documentation or seek additional support online.
