📝 Provide a clear and concise description of the issue.
Install fails with several access denied issues, along with "file not found 'requirements.txt'". According to Claude, it's because the most recent release (August 8 version 0.6.27) broke this.
What actually broke: Up through recent versions, Calibre-Web's GitHub release was a flat layout with requirements.txt and cps.py sitting at the repo root. As of 0.6.27, upstream restructured the project into a proper installable Python package: everything now lives under src/calibreweb/, dependencies are declared in pyproject.toml, and the old requirements.txt moved to src/calibreweb/requirements.txt. cps.py no longer exists at all — it's replaced by a console-script entry point (cps = calibreweb.main:main).
The community-scripts calibre-web-install.sh script hasn't caught up with this yet — it still does cd /opt/calibre-web && uv pip install -r requirements.txt, and that file simply isn't there anymore. (It would also fail later trying to run /opt/calibre-web/cps.py, since that file's gone too.) The udisks2 ... uevent: Permission denied lines earlier in your log are unrelated noise — normal for unprivileged LXC containers that can't write to /sys, and harmless.
🔄 Steps to reproduce the issue.
Run script on a Proxmox VE host.
