Plex Media Server
1

Server Version#: 1.21.2.3943
Player Version#:

I never encountered problem updading plex media server via Qnap App Center i simply click on the ADD icon, select the plex .qplg file and lauch update but from the latest version i got this error

“Failed to install Plex Media Server. QTS detected an unauthorized app change”

It might also be an APP Center issure still i don’t know where to ask for a solution.

Manual Install the file?

Yes im signed as admin and yes i download the qpkg form plex than i go in app center, clicck on Add App and select the file. The i click on INSTALL. Usually it works but now it works no more.

When is the last the QNAP has been restarted (Yes, i know they are painfully slow) ?

If it doesn’t go in app center, you can always upload and then install via the shell manually too.

Installing manually via the shell will isolate to app center’s database or the image

I reboot it today (just in case) but alas, nothing changed. I’m not an expert about shell/linux things so, there is a guide for shell install of the qpkg?

It seems i got the problem and… well… actually i found i have some network issue with may mac adapter. I got the suspect something was wrong cause all my last file in plex were corrupted. I found that the local file in my mac HD was fine and any time i copy it on qnap it was corrupted in a different place. There was no signal of issues on disk so i tried to remove lan adapter and copy files using wifi. The file were copied fine. So i tried to redownload the firmware with wifi instead of cable network and reinstalled it and it works…

The easiest way to do it is:

  1. Upload the QPKG to the Public share.
  2. SSH into the QNAP
  3. Now type these few commands:

cd /share/Public
ls *.qpkg
chmod +x Plex*.qpkg
./Plextype full part of file name here.qpkg

It looks like:

[/share/Public] # cd /share/Public
[/share/Public] # ls *.qpkg
dummy.qpkg  PlexMediaServer-0.0.0.qpkg
[/share/Public] # chmod +x Plex*.qpkg
[/share/Public] # ./Plex*.qpkg

This works because QPKG files are self-installing

You will see it check the firmware version.
If everything is OK it will continue to install itself.
