Upgrading Synology DSM From the Command Line_

October 13, 2017 @19:10

I monitor the DSM version on my Synology NAS with my icinga2 instance and sometimes alerts pop while I'm not in a position to run the upgrade using the normal GUI process.

This is rare enough that I almost always find myself trying to remember how to do it via ssh(1) and after flailing around aimlessly for a while I ultimately figure it out. This time I figured I'd write it down so I can at least find it in the future.

Basically synoupgrade is what you want.
