Synology DSM 6.2.3 Update

1 minute read

I was thinking that there hadn’t been a DSM upgrade for my DS1817+ for a while. I check the update screen quite often:

v6.2.2-24922-6 was released on 17th March 2020. Anyway, my system still says there is no new update. However, the release notes page says there is a new version, 6.2.3-25423.

Lots of changes/fixes for a point release. A highlight:

  • Added support for Let’s Encrypt wildcard certificates for Synology DDNS.

I wanted it. But how to get it?

Well, there’s the Synology download archive.

Download the pat and md5 files for your model.

Check the md5 checksum:

james@Jamess-iMac: ~/Downloads
$ DLSUM=$(md5 DSM_DS1817+_25423.pat | cut -d '=' -f2 | awk '{$1=$1};1')

james@Jamess-iMac: ~/Downloads
$ SERVERSUM=$(cat DSM_DS1817+_25423.pat.md5.txt)

james@Jamess-iMac: ~/Downloads
$ if [ "$SERVERSUM" = "$DLSUM" ]; then
> echo "md5 match";
> fi
md5 match

james@Jamess-iMac: ~/Downloads

james@Jamess-iMac: ~/Downloads
$ echo $DLSUM

Shutdown any services and docker containers. Log out of any ssh sessions and unmount any shared folders.

Click “Manual DSM Update” and select your pat file:

Click “Yes”.

Then wait, with 🤞…

For me it took about 5 minutes, then some time updating various packages.

Updated fine:

And all my docker containers started just fine:
