DSM Update Status: /dsm-update-check
/dsm-update-check queries the DSM update status — read-only and without installing anything. The command calls sudo -n /usr/syno/sbin/synoupgrade --check and translates DSM's internal status codes into readable states:
| State | Meaning |
|---|---|
| update-available | a new DSM is ready — installation deliberately only via the DSM web UI |
| up-to-date | no new DSM available |
| check-failed | the check failed — try again later |
| UNKNOWN | unclear status — check manually in the DSM web UI |
It also reports installed version, build number and small-fix number from /etc/VERSION. Passwordless sudo is required.
Why never install automatically? DSM upgrades can trigger reboots, RAID resyncs and package migrations. That decision deliberately belongs in the web UI with its safety prompts — the plugin only reports the status.
