✅ Have you read and understood the above guidelines?

yes

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

OpenWebUI

📂 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.

Trying to run "update" returns an error about the heap limit. Increasing the number at f6ca81833e/ct/openwebui.sh (L67) helps. Tried it by quickly changing it manually on my machine. You can probably figure out the right number better than I can.

🔄 Steps to reproduce the issue.

Try to run the "update" command.

❌ Paste the full error output (if available).

What size worked for you? I dont have a instance running to check. Then we can change it in the script.
