I found this script, while checking to see how to get my Plex to Auto-Update. Made some small changes, so that it checks the version to make sure it is higher & not just different. Also did some formatting & removed the sleep function as it is a hack, imo.
Here is the updated version - https://github.com/nitantsoni/plexupdate -
Thanks for the advice! The part that gets the Plex Token still wasnât working for me, so I just found it manually and pasted it in (I guess it doesnât change?) The script seems to run through happily now without errors, finding the correct current and new versions numbers - so I just need to wait for Plex to release an update to see if the downloading / updating part works ⊠!
Brekus,
Quick question: How did the variable â$tokenâ, get set, in your example?
To clarify, the following link describes the process for determining your own plex-pass-token, however, I was just wondering if you declared $token as an absolute earlier in your script, and didnât include that declaraion (for obvious reasons), or if you had a programatic mechanism for dynamically retrieving your token, in the script (which now that I say itâŠseems unlikely).
Thanks.

Sorry @monkeyhat, I edited my comment to fix the method for finding your PMS directory and extracting the token.
$token was set by using this line from the original post. I havenât had to change it as it has been working for me without issue. I see others are having issues not sure why though.
token=$(cat /volume1/Plex/Library/Application\ Support/Plex\ Media\ Server/Preferences.xml | grep -oP âPlexOnlineToken="\K[^"]+â)
I did however have to change my volume since I have plex installed on another one.
I try the script with the last update and get 289 error code when install
I use the last version of https://github.com/martinorob/plexupdate
Some one has the same error?

Try this:
Thank you. That worked.
Hey @euphnutz - just wanted to say, there was a Plex server update today for the first time since I added this script, ant it worked perfectly. So thanks for your help!
I gave up on the script since itâs not exactly built for aarch.
EDIT: Looks like yours isnât doing plex-pass versions, the original is, makes sense. Carry on, ha. I do like how yours is written to help weed out any bugs, very clean. Much appreciated!
I added the token line and updated the URL, now its appearing and working as expected:
token=$(cat /volume1/Plex/Library/Application\ Support/Plex\ Media\ Server/Preferences.xml | grep -oP âPlexOnlineToken=â\K[^â]+â)
url=âhttps://plex.tv/api/downloads/5.json?channel=plexpass&X-Plex-Token=$tokenâ
I tried yours, but with the recent update it outputs the following:
root@NAS01:/volume1/Scripts# bash plexupdate-new.sh
Latest version: 1.18.1.2019
Current version: 1.18.2.2029
No new version available
Not sure why yours shows an old version?
Martinoâs original script outputs:
root@NAS01:/volume1/Scripts# bash plexupdate.sh
New Ver: 1.18.2.2029-36236cc4c
Cur Ver: 1.18.2.2029-36236cc4c

Hey there, once included all of the modifications above @mpalensh , today there is an update, however I can see the following error.
New version: 1.18.2.2029-36236cc4c
Current version: 1.18.2.2015-5a99a9a46
New version available!
parse error: Invalid numeric literal at line 1, column 4
http://: Invalid host name.
Failed to install package /tmp/plex/*.spk, error = [150]
I can see the script has an https:// to be honest, not sure why you would see that http:// to be honestâŠ
To be clear, my full, modifications included, script, follows.
#!/bin/bash
mkdir -p /tmp/plex/
TOKEN=$(cat /volume1/Plex/Library/Application\ Support/Plex\ Media\ Server/Preferences.xml | grep -oP 'PlexOnlineToken="\K[^"]+')
URL=$(echo "https://plex.tv/api/downloads/5.json?channel=plexpass&X-Plex-Token=${TOKEN}")
JSON=$(curl -s ${URL})
NEW_VERSION=$(echo $JSON | jq -r .nas.Synology.version)
echo "New version: ${NEW_VERSION}"
CURRENT_VERSION=$(synopkg version "Plex Media Server")
echo "Current version: ${CURRENT_VERSION}"
if [[ "${NEW_VERSION}" > "${CURRENT_VERSION}" ]]; then
echo "New version available!"
/usr/syno/bin/synonotify PKGHasUpgrade '{"[%HOSTNAME%]": $(hostname), "[%OSNAME%]": "Synology", "[%PKG_HAS_UPDATE%]": "Plex", "[%COMPANY_NAME%]": "Synology"}'
cpu=$(uname -m)
URL=$(echo â${JSON}â | jq -r '.nas.Synology.releases[] | select(.build=="linux-'"${CPU}"'") | .url')
/bin/wget "$url" -P /tmp/plex/
/usr/syno/bin/synopkg install /tmp/plex/*.spk && /usr/syno/bin/synopkg start "Plex Media Server" && rm -rf /tmp/plex/
else
echo "Plex is up to date."
fi
exit 0
Any idea 
?
[edit]
Changing
URL=$(echo â${JSON}â | jq -r '.nas.Synology.releases[] | select(.build=="linux-'"${CPU}"'") | .url')
to
URL=$(echo "${JSON}" | jq -r '.nas.Synology.releases[] | select(.build=="linux-'"${CPU}"'") | .url')
did remove the parsing error, however wget is still lamenting an invalid http:// host name.
@ErMeglio you need to be sure that when you reference your variables (cpu and CPU below) that they are the same case as when they are declared:
cpu=$(uname -m)
URL=$(echo "${JSON}" | jq -r '.nas.Synology.releases[] | select(.build=="linux-'"${CPU}"'") | .url')
Also, you should change this line:
TOKEN=$(cat /volume1/Plex/Library/Application\ Support/Plex\ Media\ Server/Preferences.xml | grep -oP 'PlexOnlineToken="\K[^"]+')
To this so that it intelligently finds your PMS install dir:
PMS_PATH=$(find / -path '*/Plex Media Server' -print -quit 2>/dev/null)
TOKEN=$(grep -Po 'PlexOnlineToken="\K[^"]+' "${PMS_PATH}"/Preferences.xml)
Thanks a lot for the help @euphnutz !
Unfortunately this line still doesnât work:
URL=$(echo â${JSON}â | jq -r '.nas.Synology.releases[] | select(.build=="linux-'"${CPU}"'") | .url')
as it returns the following:
New version: 1.18.2.2029-36236cc4c
Current version: 1.18.2.2015-5a99a9a46
New version available!

The tip re. the case has still helped me resolve by swapping to the standard double quotes around ${JSON}:
URL=$(echo "${JSON}" | jq -r '.nas.Synology.releases[] | select(.build=="linux-'"${CPU}"'") | .url')
The update has gone through - happy days 
@ErMeglio did you change this line?
cpu=$(uname -m)
To this?:
CPU=$(uname -m)
The quoting in the jq statement is not the issue. Your variable needs to be all caps since you reference it in all caps in the jq statement.
Hey, thanks for the follow-up! I had changed CPU to capitals after learning capitals do matter, yes
However nope, the line
URL=$(echo â${JSON}â | jq -r '.nas.Synology.releases[] | select(.build=="linux-'"${CPU}"'") | .url')
was throwing the error:
parse error: Invalid numeric literal at line 1, column 4
so I have simply changed it to:
URL=$(echo "${JSON}" | jq -r '.nas.Synology.releases[] | select(.build=="linux-'"${CPU}"'") | .url')
and it all works well now!
Weird. The 2 lines look exactly the same to me. 
Glad itâs working for you now.
Edit: Ohhh, I see now. There are some weird quotes surrounding ${JSON} in the non-working example.
Edit 2: I fixed it in my previous comments.
Worked like a charmâŠTHANK YOU Nitantsoni and Martino!
