As usual when a new Synology DSM Update comes out, I got a notification email telling me that a new update (6.0-7321-1) was available for my DS213j NAS:

Dear user,

A new version of DSM has been downloaded and is ready to install. Please sign into ds213j and go to Control Panel > Update & Restore to install DSM 6.0-7321 Update 1. To know more about the DSM update, please refer to https://update.synology.com/autoupdate/whatsnew.php?model=DS213j&language=enu.

Sincerely,

Synology DiskStation

So, as usual, I signed into the DSM web interface but when I tried to go to the Update & Restore menu, I got this:

Your DSM version is up-to-date.

Since I was signed in as an administrator, this couldn’t be a permission issue.I thought that perhaps Synology had pulled the update for whatever reason (even though I couldn’t find anything about this online), but the release notes as of today still show this update.

So I started looking for the update file to do a manual update, but apparently the file for version 6.0-7321-1 are not there. If you go to the official Synology DS213jdownload page, you will be prompted to download a .pat file for version 6.0-7321 of DSM. And if you look at all the available versions of DSM, you can only see updates up to version 6.0-7321.

Does anyone know what happened to this update? If you do, it would be great if you could let me know with a comment below.

Update 21/04/2016

It turns out that there was indeed an issue with this update. A new update (6.0-7321-2) was released on April 18th that fixes an issue with the previous update pack. From the updated release notes:

Fixed an issue where DSM 6.0-7321 Update 1 could not be normally installed with Auto-Update.

After installing this, my DSM now shows the correct updated version:

DSM 6.0-7321 Update 2
