✅ Have you read and understood the above guidelines?

yes

📜 What is the name of the script you are using?

Open WebUI

📂 What was the exact command used to execute the script?

update

⚙️ What settings are you using?

Default Settings
Advanced Settings

🖥️ Which Linux distribution are you using?

Debian 12

📝 Provide a clear and concise description of the issue.

I ran the update command to upgrade Open WebUI to v0.6.11. The command failed with an error, so I tried it again. This time, it displayed the following messages:
✔️ Ollama is already up to date.
✔️ Open WebUI is already up to date.

However, after the update, Open WebUI stopped working. The browser shows an error saying "This site can’t be reached" when visiting: 192.168.1.5:8080.

I then tried to manually start the service /opt/open-webui/backend/start.sh and received the following error:

Thank you, it worked!

It seems update does not install new requirements. starlette-compress was added yesterday to requirements.txt for Open WebUI v.0.6.11 (commit 4da75a9). After I removed the EXTERNALLY-MANAGED file and reran pip3 install -r requirements.txt -U, the system installed and updated the following modules:
