The root helper counted updated packages from the last 2,000 characters of the package manager's output. Every manager prints its count (apt's "N upgraded, N newly installed", dnf's "Upgrade N Packages", zypper's "N packages to upgrade", pacman's "Packages (N)") before the long log of what it then does, so a large update pushed the line out of the tail and the job recorded no count. Docker03's 2026-11-01 job applied 17 updates and reported none; Docker02's single package was counted. The update steps now read their whole output (run(keep=None)), and only the failure text and the job's detail are cut short. Agent 1.26.1, so hosts show the helper as an update to take.
