Package: libnginx-mod-http-modsecurity Version: 1.0.3-2+b2 Severity: important Tags: trixie
Upgrading bookworm -> trixie, libnginx-mod-http-modsecurity triggers a circular dependency-like issue and the upgrade is unable to complete: dpkg: error processing package nginx (--configure): installed nginx package post-installation script subprocess returned error exit status 1 dpkg: dependency problems prevent configuration of libnginx-mod-http-ndk: libnginx-mod-http-ndk depends on nginx-abi-1.26.3-1; however: Package nginx-abi-1.26.3-1 is not installed. Package nginx which provides nginx-abi-1.26.3-1 is not configured yet. dpkg: error processing package libnginx-mod-http-ndk (--configure): dependency problems - leaving unconfigured dpkg: dependency problems prevent configuration of libnginx-mod-http-modsecurity: libnginx-mod-http-modsecurity depends on libnginx-mod-http-ndk; however: Package libnginx-mod-http-ndk is not configured yet. libnginx-mod-http-modsecurity depends on nginx-abi-1.26.3-1; however: Package nginx-abi-1.26.3-1 is not installed. Package nginx which provides nginx-abi-1.26.3-1 is not configured yet. dpkg: error processing package libnginx-mod-http-modsecurity (--configure): dependency problems - leaving unconfigured Errors were encountered while processing: nginx libnginx-mod-http-ndk libnginx-mod-http-modsecurity Error: Sub-process /usr/bin/dpkg returned an error code (1) It appears libnginx-mod-http-modsecurity depends on the next version of nginx, which cannot start until libnginx-mod-http-modsecurity is fully installed. A workaround appears to be: 1. Remove packages libnginx-mod-http-modsecurity & libnginx-mod-http-ndk 2. Edit nginx.conf to temporarily disable modsecurity which is now missing. 3. Re-run upgrade to allow it to complete, and nginx to start successfully. 4. Reinstall libnginx-mod-http-modsecurity & modsecurity-crs (if installed) 5. Make any necessary changes (I had some breakage in /usr/share/modsecurity-crs/owasp-crs.load) 6. Re-enable modsecurity in nginx.conf 7. Restart necessary services.
