I cannot reinstall Plex

Plex Media Server NAS & Devices
1

Server Version#: DSM 7.2.2-72806 Update 4
Player Version#: Plex Media Server for Synology (DSM 7.2.2+)

Since the latest DSM update in February, I’ve been unable to reinstall Plex Media Server on my Synology DS418 NAS. I’ve spent days doing multiple variations of the following with no luck:

  1. changed permissions on the shared plex directories as shown in the troubleshooting guide (at the beginning, when they existed)
  2. uninstalled everything, but the two folders remained, so i manually deleted both via root SSH commands (and the two @Plex files as well)
  3. the uninstall option no longer exists, so i’ve tried to re-install multiple versions between the Synology Package “searched” version and PlexMediaServer-1.41.4.9463-630c9f557-aarch64_DSM72.spk through the latest PlexMediaServer-1.42.1.10060-4e8b05daf-aarch64_DSM72.spk. Both give the generic Failed to install “Plex Media Server” messages. Server logs don’t give any useful information.
  4. I’ve spent literally days on multiple forums trying to find a solution.

Can you assist please?

Did you go into Control Panel - Shared Folder
and DELETE the PlexMediaServer shared folder ?

You must be an administrator to do this.

If you delete it using the SSH command line without removing it from the DSM database, nothing will work right.

Thank you so much for the fast reply. Yes,I deleted via shared folder first.

I’m in New York time zone so this will be a bit offset but we’ll get there.

When you tried to reinstall, what error did you get?

Did you select correct CPU class ( ARM64 )?

Hello, I’ve been using the ARMv8 as directed by Google AI… oh no, I’m going to feel very stupid if this is the solution!

Because of the share deletions, the NAS is (still) reclaiming the space (24 hrs later, what’s up with that?), so it’s made all my drives Read-Only mode.

I’ll try to manually install the 64ver as soon as it finishes (how long will that be do you think?).

Thank you again for the fast reply! :grinning_face:

@Daveychan

There are multiple versions of Plex for DSM 7.

You show DSM 7.2.2

Therefore.

This would be the file you want to download

https://downloads.plex.tv/plex-media-server-new/1.42.1.10060-4e8b05daf/synology-dsm72/PlexMediaServer-1.42.1.10060-4e8b05daf-aarch64_DSM72.spk

Once downloaded, do a Manual Install in Package Center.

If you’re still having problems, we’ll find a way to clear out the DSM mess

I’ve just tried to manually install the SPK from the link you sent. Unfortunately I get the same, Failed to install “Plex Media Server” error.

Edit 1: It’s now doing Data Scrubbing after the reclamation…. i’ll try again when that finishes

Edit 2: No joy, same error.

@Daveychan

Are you around so we can get this done?

10

Unfortunately, I’m at work. However, I woke up to a beeping NAS this morning. Apparently the scrubbing failed and the volume is read-only now. I tried two reboots before leaving the house. Please tell me I don’t have to delete, remake,and restore from backup…. :pleading_face:

Hey,
Just finished dinner.

You have time?

How do we want to do the audio ? (whatsapp or facetime ?)
How do we want to do the desktop sharing? (AnyDesk or RustDesk) ?

19

Hello, excellent, thanks - how about teamviewer?

20

Teamviewer has banned me from using it (I’ve helped too many people)

21

LOL - okay, i haven’t used anydesk or rustdesk, but can quickly install either
