Latest autoupdate image does not work
Host OS: Linux (Ubuntu 16.04) Tag/Version: autoupdate
Steps:
- Create a new container using the following command:
docker run -d --name=plex --restart=unless-stopped -v /plex:/config -v /media:/media -p 1900:1900/udp -p 32469:32469 -p 3005:3005 -p 5353:5353/udp -p 8324:8324 -p 32410:32410/udp -p 32412:32412/udp -p 32413:32413/udp -p 32414:32414/udp -p 32400:32400 -e X_PLEX_TOKEN=<token> wernight/plex-media-server:autoupdate
Expected: Server to download latest plex pass version and run.
Actual: The following error:

Thanks for helping and maintaining this image btw!
I'm having a similar issue:

Last version for PlexPass seems to have an issue. Until it's fixed by Plex, you can do one of:
- Set
PLEX_FORCE_DOWNLOAD_URL=https://plex.tv/downloads/latest/1?channel=8&build=linux-ubuntu-x86_64&distro=ubuntu - Remove
X_PLEX_TOKEN
the container and Plex is working again, however it seems that Plex Pass updates are not downloaded and/or installed.
Plex version 1.7.4.4017-3886b5c85 for Ubuntu 64 (sha1 c9d3d4a709a30b86f144c5f59b6894bd5ba89b3f matching what's on https://www.plex.tv/downloads/) cannot be installed. This is a new issue as version 1.5.7.4016-25d94bad9 works.
Posted the issue also on Plex forum.
Thank you for the help! I guess this ticket could be closed since it's not an issue on your end, but you could also leave it open for visibility until Plex resolves the underlying issue; up to you :)
As a workaround I am using the "latest" image instead of autoupdate and it works just fine.
@gravufo I suggested 2 other workarounds. I'll leave it open until resolved.
Plex seems to have updated, but the docker still seems unable to install PMS.
If I run the docker using X_PLEX_TOKEN, this is the error:

Same issue here on 1.7.4 and 1.7.5.4035-313f93718.
The error in the post script is because of udev / udevadm. Here's the debug output of the post install script (running with configure, non-existing PMS installed so far):
+ action=configure
+ version=
+ [ = 1 ]
+ [ x = x ]
+ USER=plex
+ getent passwd plex
+ getent group plex
+ [ ! -d /var/lib/plexmediaserver ]
+ PUSER=plex
+ VGROUP=video
+ NORUN=0
+ OVERRIDE=/etc/systemd/system/plexmediaserver.service.d/override.conf
+ OLDSERVICE=/etc/systemd/system/plexmediaserver.service
+ OLDINIT=/etc/default/plexmediaserver
+ cat /proc/1/comm
+ [ bash = systemd ]
+ [ -f /etc/default/plexmediaserver ]
+ grep ^User= /etc/default/plexmediaserver
+ wc -l
+ [ 0 = 1 ]
+ [ -f /dev/dri/renderD128 ]
+ [ -f /dev/fb0 ]
+ [ -f /dev/video0 ]
+ [ 0 != 1 ]
+ getent group video
+ grep -c video
+ [ 1 != 0 ]
+ groups plex
+ grep -c video
+ [ 1 = 0 ]
+ [ -f /etc/systemd/system/plexmediaserver.service ]
+ [ -f /sbin/udevadm ]
+ udevadm control --reload-rules
Udev won't start in Docker containers and therefor the following command fails:
root@02e47a391c55:/# udevadm control --reload-rules
root@02e47a391c55:/# echo $?
2
I remember creating a dummy start for example. May be a dummy udev or udevadm would fix this.
Mhm could work…
Just FYI: I'm not using your image, as I'm using my own Docker image. However, I've the same problem and when I saw your issue I though I will update it ;)
I see the following options:
- Replace
udevadmwith a dummy script which exits with code0 - Create an
udevadmwrapper script around the originudevadmwhich returns always with exit code0 - Force installing plex
- Wait until the issue is fixed, as it's already addressed
IMHO you don't need to tinker with the udev init script, as the post-install script will only use udevadm. Unfortunately, there's a set -e set on top, and because of that it fails.
As we're talking about Docker, I would suggest replacing udevadm with a dummy script is an option, as well as force installing plex. However, I wait until it's fixed! :)
Hi,
I've tried 3 different methods of running the container (token, log in credentials, forced download URL), and get the same error message with all three:

You can use also wernight/plex-media-server:latest. 1.7.5 has the issue described here.
I've just pushed a temp fix until this is properly fixed. You may pull to test the new version.
It might be decent to exit/fail after n number of tries, to prevent unneeded bandwidth consumption. Woke up this morning to find nearly 300GB consumed attempting to download/install from the autoupdate image.
@adduc This is not directly the image's fault, it's how Docker works. However, auto-updating images aren't a good practice, as Docker wasn't designed for that ;) Auto-updating means your image will grow over time and you can't leverage the Docker FS layers.
@domibarton The image will not grow over time. You just need to clean up unused images which not docker have docker image prune.
There is a non-autoupdate but that should work for plex pass as those download links are normally restricted. Also it may delay updates.
@adduc That's if you've setup restart:true without delay. I don't see a good way to make that work simply. There could be of course such mechanism within the auto-update image but I feel it's not the right place. For example it'd give no way from outside the container to just see that it failed to download. So I think it should be done outside of the container. Kubernetes for example automatically multiplies time by 2 each time.
What could be done is to have the downloaded .deb cached. It'd also improve restart speed. I'll look into supporting that.
