A dashboard-triggered update that failed on the host left the /update-progress
page spinning to a vague 10-minute timeout — no error was ever shown, because
nothing wrote a failure marker for the page to read. Fix: make failures visible
and prevent the credential-prompt hang class.
- docker/restart-sentinel/watch.sh: run update.sh under `timeout -k 30 1800` with
its output tee'd to run/update.log; on ANY non-zero exit (update.sh or its
exec'd install.sh) — and on the early compose-missing / updater-missing paths —
write {"stage":"error"} to run/update-phase.json via write_update_error().
- update.sh: export GIT_TERMINAL_PROMPT=0 + GIT_HTTP_LOW_SPEED_* and wrap the pull
in `timeout 300`, so a private-repo credential miss fails fast instead of
hanging on a non-interactive prompt.
- DeploymentService::updatePhase(): whitelist the 'error' stage.
- update-progress.blade.php: add an error state (#js-status-error) + showError();
the status-feed poll now stops and shows it on stage=error, marking the active
phase red — instead of looping.
- lang/{en,de}/update.php: error_heading / error_hint / back_button.
- UpdateProgressTest: feed surfaces stage=error; page renders the error branch.
