Check Existing Issues

  • I have searched for any existing and/or related issues.
  • 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

Docker

Open WebUI Version

v0.8.12

Ollama Version (if applicable)

No response

Operating System

Ubuntu 22.04,

Browser (if applicable)

No response

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

Container starts successfully, same as v0.8.10.

Actual Behavior

Starting from v0.8.11, the container crashes immediately on startup with:

ImportError: cannot load module more than once per process

Steps to Reproduce

  1. Use the official Docker image ghcr.io/open-webui/open-webui:v0.8.11 or v0.8.12
  2. Run with docker compose up
  3. Container exits immediately with code 0

Got the same error too, downgrade to 0.8.10 will fix the issue, but 0.8.11 and 0.8.12 were broken.

@bennodepenno commented on GitHub (Mar 28, 2026):

I ran into the same issue. In my case, since I'm running open-webui using docker in a Virtual Machine, I looked at the CPU setting of the VM which was set to qemu64. Changing it to x86-64-v2-AES (providing access to some CPU features which would otherwise be shielded) solved the issue for me. If you are running open-webui as a container inside a VM, this might be worth looking into.

Same issue, but I can't use the CPU setting referenced above because I'm running it on ancient hardware.

I also hit this in Proxmox just now with the latest image running a Debian VM for my docker.

I was running the default kvm64 cpu type and changing it to x86-64-v2-AES also let openwebui run successfully.

Using Proxmox with Ubuntu, changing the default cpu to x86-64-v2-AES fixed it

As I am also running on ancient hardware (Intel Core i7-930 circa 2010), changing the default CPU likewise did not work for me. Downgrading to 0.8.10 suffices for now.

I'm getting this issue as well. I've tried manually "patching" it by installing an older numpy with pip in the container, but the container doesn't actually stay running long enough for that to actually work.

Thanks @bennodepenno - I was tearing my hair out wondering why it was working on my desktop but not when I moved it to the server a week later.
