Community Cloud deployment blocked by expired bullseye-security metadata

Hello,

My Streamlit Community Cloud app cannot deploy because the build fails during APT dependency installation.

Error:

E: Release file for
http://deb.debian.org/debian-security/dists/bullseye-security/InRelease
is expired

The failure occurs before Python dependencies are installed and before the app starts.

Environment

  • Branch: main

  • Python: 3.12

  • packages.txt:

    • fonts-noto-cjk

    • fonts-wqy-zenhei

I have already:

  • changed Python from 3.14 to 3.12;

  • redeployed the app;

  • completely recreated the Streamlit Cloud app.

The same APT error still occurs.

These font packages are required by the application for CJK font rendering in ReportLab PDF generation, so they cannot simply be removed as a workaround.

Could you please check whether there is an issue with the Community Cloud APT/base-image environment, particularly the bullseye-security repository metadata?

Thank you.
