The components that can be configured are `orbit`, `osqueryd` and `desktop` (Fleet Desktop). When one of these components is omitted in `update_channels` then `stable` is assumed as the value for such component. +New agents default to the latest versions unless specific versions are set in the `fleetctl package` command. If `update_channels` specifies versions, agents will use those instead, even if it means downgrading (e.g., generating at 1.53.1 but enrolling with `update_channels.orbit` set to 1.50.0). + > Because Fleet moved the update server from tuf.fleetctl.com to updates.fleetdm.com, Orbit versions below 1.38.1 can’t upgrade directly to newer versions. You’ll see this error in Orbit logs: `update failed error="lookup failed: lookup orbit: tuf: file not found`. To upgrade from a version below 1.38.1 (e.g., 1.29.1) to a newer version (e.g., 1.50.2), first upgrade to 1.38.1, wait for agents to update, then upgrade to the newer version. #### Examples
