I have searched for any existing and/or related discussions.
I have also searched in the CLOSED issues AND CLOSED discussions and found no related items (your issue might already be addressed on the development branch!).
I am using the latest version of Open WebUI.

Installation Method

Git Clone

Open WebUI Version

0.8.3

Ollama Version (if applicable)

0.16.2

Operating System

Ubuntu 25.10

Browser (if applicable)

Vivaldi

Confirmation

I have read and followed all instructions in README.md.
I am using the latest version of both Open WebUI and Ollama.
I have included the browser console logs.
I have included the Docker container logs.
I have provided every relevant configuration, setting, and environment variable used in my setup.
I have clearly listed every relevant configuration, custom setting, environment variable, and command-line option that influences my setup (such as Docker Compose overrides, .env values, browser settings, authentication configurations, etc).
I have documented step-by-step reproduction instructions that are precise, sequential, and leave nothing to interpretation. My steps:
Start with the initial platform/version/OS and dependencies used,
Specify exact install/launch/configure commands,
List URLs visited, user input (incl. example values/emails/passwords if needed),
Describe all options and toggles enabled or changed,
Include any files or environmental changes,
Identify the expected and actual result at each stage,
Ensure any reasonably skilled user can follow and hit the same issue.

Expected Behavior

No SyntaxWarning warnings in open-webui.log file.

Actual Behavior

Multiple SyntaxWarning warnings in open-webui.log file for pydub package.

Steps to Reproduce

Start Open WebUI
Check open-webui.log file
Near the top it should show these errors

Logs & Screenshots

Additional Information

Python version: 3.12

I can fix the issue with

user@user-linux:~$ uvx --python 3.12 uv pip install --upgrade pydub
Installed 1 package in 1ms
Resolved 1 package in 88ms
Prepared 1 package in 30ms
Installed 1 package in 0.88ms
 + pydub==0.25.1

but after Open WebUI upgrade it comes back again.

Perhaps a more precise version should be defined in the requirements.txt file for the pydub package?
