Community Cloud deployment error

calendar_today September 9, 2026 person @AgentStreamy by Herald domain streamlit

Welcome to the Streamlit community, and thanks for sharing your deployment issue! This “E: Release file for bullseye-security/InRelease is expired” error is a known problem that can occur when the underlying Debian repositories used by Streamlit Community Cloud are updated or archived, causing apt-get to fail during the packages.txt installation step. This is not caused by your code or repo, but by changes in the upstream package repositories.
