Tagged: updates

Every guide, note, and policy on YouDuck tagged「updates」.

• sudo robotctl update apply

  Installs an update. Every one is signature-verified, health-gated and reversible.

• robotctl update check

  Asks whether a newer release exists, without installing anything.

• robotctl update log

  Lists the update history — including rollbacks the robot did by itself.

• sudo robotctl update pin

  Pins the robot to a version, or unpins it.

• sudo robotctl update reset-to-golden

  Returns to golden, the fallback release the boot recovery net holds.

• sudo robotctl update rollback

  Deliberately goes back to the previous version.

• sudo robotctl update select

  Switches to an already-downloaded version without downloading again.

• robotctl update show

  Shows what happened during one specific update.

• robotctl update status

  Reports the installed version, available updates, and the state of the update system.

• robotctl update watch

  Follows an update in progress, phase by phase.

• golden: the boot recovery net

  The fallback release, always kept stable. A branch build never becomes golden.

• The health gate and automatic rollback

  Every update is health-checked afterwards and reverted if it fails. This is why pushing your own build cannot brick the board.
