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
open-webui launches.
Actual Behavior
open-webui crashes during startup with ModuleNotFoundError: No module named 'aiosqlite'. (See logs for the traceback.)
Steps to Reproduce
Start with open-webui v0.8.12. It was working at this point. (This step probably isn't necessary but I'm documenting it anyway.) The Python version is 3.13.11. I do not know exactly what the versions were of all the dependencies since open-webui does not pin them.
Upgrade to open-webui v0.9.0 using uv tool upgrade --all. (See attached logs for exact versions of all dependencies used.) This was run at 2:09 AM Pacific Daylight Time, UTC-7.
Run open-webui serve. (I tested removing the environment variables and flags shown in the logs, but the error is the exact same.)
Logs & Screenshots
Here are my terminal logs when I updated open-webui using uv and attempted to launch it. Because it crashed during launch, browser console logs are not applicable. I am not using Docker.
