Feb 1, 2026February 2026 monthly summary for cockpit-project/bots focused on strengthening packaging reliability, security posture, and developer workflow in Debian and RPM environments. Delivered four key items: Debian-testing image package management improvements restoring sss and ipa packages and removing deprecated packagekit-tools; HTML rendering/security enhancements escaping computed values in templates and improving log handling for non-string values; a testing workflow improvement to allow unsigned RPMs to speed development/testing; and a critical fix to sudo/sssd permissions in Debian testing by updating nsswitch.conf. These changes reduce installation friction and runtime errors, harden content rendering against XSS, accelerate development cycles, and improve admin reliability in testing environments. Technologies demonstrated include Debian packaging practices, RPM development/testing pipelines, HTML templating with escaping (Mustache-like), safe log rendering, and sssd/sudo configuration. Business value delivered includes faster iteration, safer dynamic content rendering, and more robust admin operations across Debian testing and development workflows.

Aug 1, 2025Monthly work summary for 2025-08 focusing on the cockpit-project/bots repository. Key change implemented to improve Debian compatibility for System Diagnostics Tools installation. Updated installation script to install 'sos' instead of 'sosreport' on newer Debian versions to avoid util-linux-related issues and ensure system diagnostic tools are available. This reduces install-time failures and improves reliability of fleet diagnostics provisioning. No additional user-facing features were delivered this month beyond the compatibility fix.
