When updating or installing PolicyD on Debian 12, you might encounter an error related to the use of the deprecated function yaml.load. This error may appear as follows: “policyd-rate-limit: Uses deprecated yaml.load.” Fortunately, there is a simple solution to address this issue.
This step-by-step guide will show you how to resolve this error and successfully update PolicyD.
Step 1: Access the Console or SSH
Ensure you are connected 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 utils.py file where the deprecated reference to yaml.load is located.
sudo nano /usr/lib/python3/dist-packages/policyd_rate_limit/utils.pyStep 3: Replace yaml.load
Search the file for the code that uses yaml.load. You’ll likely find it in a section that loads YAML settings or configurations. Replace this line with 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 Nano’s specific commands (Ctrl + O to save, then Ctrl + X to exit).
Step 4: Restart PolicyD
To apply the changes, restart the PolicyD service. You can do this using the following command:
sudo systemctl restart policydStep 5: Verification
Once the restart is complete, verify that the error has been resolved. You can do this by checking the system logs or by rerunning the command that initially caused the error.
Bonus: One-Line Command Modification with SED
sudo sed -i 's/yaml\.load/yaml\.full_load/g' /usr/lib/python3/dist-packages/policyd_rate_limit/utils.py- sudo: Executes the command as an administrator, since we need to modify a system file.
- sed: The command-line tool used for text substitutions.
- -i: Tells
sedto modify the file in place. 's/yaml\.load/yaml\.full_load/g': This is the substitution expression. It searches for all instances ofyaml.loadand replaces them withyaml.full_load. Thegat the end indicates that this should be done globally, i.e., for all occurrences on each line./usr/lib/python3/dist-packages/policyd_rate_limit/utils.py: The path to theutils.pyfile 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. Make sure to check that PolicyD is functioning correctly after the update. If you encounter any other issues or errors, refer to the official PolicyD documentation or seek additional assistance online.
