Plex Update script to simplify the life of Linux Plex Media Server users.

plexupdate's Issues

If you use .plexupdate config file and have problems updating plex...

If you're using a .plexupdate configuration file in your home directory and that file specifies the release with RELEASE=, then be sure to change it from RELEASE=64-bit to RELEASE=64. Otherwise you'll get the error Sorry, page layout must have changed, I'm unable to retrieve the URL needed for download.

Update failed with latest update (0.9.2.11.1406-8403350)

I tried the script on both of my Ubuntu boxes this evening. Note: Script worked fine last upgrade.

I checked GIT for an update, then ran the script this evening. (although in briefly looking at the code, it's got an auto-updater now?)

All it seemed to do is download the upgrade file, but didn't go any further. No error message, until I thought I'd made a mistake and tried it again. Then it was kind of upset that the file to download was already there. :)

Automatic script update

Is there a possibility to make this script auto updating, for example every time the user runs the script it will download a new version if available. Could be directly from github.

I'm not into bash script or Linux programming, but I can take a look if I can make a start.

User Credentials

Is the username and password for the server that pms is being installed on?

download doesn't work

I think plex team had made some modification on the plex pass web site:
now the release value must be set to RELEASE="64 bit" instead of 64-bit

Plex Pass authentication failing

Something is wrong with the plexpass authentication. Posts at the end of this thread explain that the new website has changed something and with the current script setup the failed authentication just returns the non plex pass version.

Problem with Download directory

My .plexupdate file contains:
DOWNLOADDIR="/data/plexmediaserver/Library/Application Support/Plex Media Server"

When I try to run plexupdate I'm getting:
Error: Download directory does not exist or is not a directory

I noticed you committed a change recently for checking the download directory. On line 136 you are doing eval pushd. I tried this command by itself in the bash prompt with my directory and got this:
bash> eval pushd "/data/plexmediaserver/Library/Application Support/Plex Media Server"
-bash: pushd: /data/plexmediaserver/Library/Application: No such file or directory

I then tried the same command but without the eval part and it worked fine. So I tried removing the eval command on line 136 so it just says pushd and the script ran fine for me. Not sure exactly what is happening, but I think it has to do with spaces being in my path. Why is the eval there and is it necessary? The script only runs for me if it's not there.

Check plex current usage before updating

I'm currently using a wrapper script to validate that Plex is not in use before running this script. I utilize the plexwatch tool, but it would be cool if this had something built in. I may have modified your original script as well, to make it work smoother with the wrapper. Will check if you're interested

Get rid of -S

Just opening this as an issue before sending in a PR to see if there are any objections. -S seems completely unnecessary for experienced users, and dangerous for inexperienced ones. If you know what you're doing, ./plexupdate.sh -q 2>/dev/null does exactly the same thing. If you don't know what you're doing, -S only serves to hide all possible output from you which seems like a terrible idea.

It looks like it was added in #53 with the comment "Added a silent mode argument (because why not?)", which just seems like the worst possible reason to ever add anything to a piece of software.

yum waits for confirmation before update on CentOS

Great work on the script, just fantastic! I may be running this wrong but yum waits for you to accept the install before it will update the RPM package.

OS: CentOS 6.6

Scenario: Run .sh script with -a option

Issue: Script will download and hang on yum install screen. Waiting for you press "y/n" to accept the new RPM install.

Workaround: Modify line #285
From: sudo yum localinstall "${DOWNLOADDIR}/${FILENAME}"
To: sudo yum -y localinstall "${DOWNLOADDIR}/${FILENAME}"

The -y option auto accepts yum messages.

Using ~ in quoted DOWNLOADDIR causes download to fail

This is an error not caused by the script itself, but by how wget and/or the shell treats this value.

The typical error an end-user sees is this:

$ ./plexupdate.sh   
Authenticating...OK
Finding download URL for 64-bit...OK
 !! Download failed with code 1, "~/.plexupdates/plexmediaserver_0.9.12.12.1459-49fe448_amd64.deb: No such file or directory"

This can be reproduced independently from the script itself:

# quoted with ~, fails
$ wget -O "~/.plexdownloads/test1.deb" 
https://downloads.plex.tv/plex-media-server/0.9.12.11.1406-8403350/plexmediaserver_0.9.12.11.1406-8403350_amd64.deb

# unquoted with ~, succeeds
$ wget -O ~/.plexdownloads/test2.deb 
https://downloads.plex.tv/plex-media-server/0.9.12.11.1406-8403350/plexmediaserver_0.9.12.11.1406-8403350_amd64.deb

# expanded ~ with quotes, succeeds
$ wget -O "/home/user/.plexdownloads/test3.deb" 
https://downloads.plex.tv/plex-media-server/0.9.12.11.1406-8403350/plexmediaserver_0.9.12.11.1406-8403350_amd64.deb

Since we really want to be quoting our strings, the remaining option is to expand the DOWNLOADDIR-variable ourselves, and for now that is also a reasonable manual workaround, but it should be documented.

For the future, the script should be able to apply this workaround itself.

Ubuntu 16.04

All of a sudden started getting this error. Any ideas?

Thanks for the useful update script!

Script stuck on Auto updating

It seems the script is stuck at auto updating, I always get "Auto updating...OK" out from the script, multiple times after each other (seems like it never moves on to the next phase).

Playing around with some stuff I first thought it was because I had my config and log file moved into the same folder, but when I remove the location of my .plexupdate file from the command, it seems to be working just fine again.

Also disabling Auto update in the config file, and specifying the config's location does work.

EDIT: After some more investigating, it seems that the problem originates from here: https://github.com/mrworf/plexupdate/blob/master/plexupdate.sh#L233

this is the log I get when I print out the ALLARGS variable:

Auto updating...OK
../.plexupdate
Auto updating...OK
../.plexupdate -U
Auto updating...OK
../.plexupdate -U -U
Auto updating...OK
../.plexupdate -U -U -U

../.plexupdate -U -U -U -U
Auto updating...OK
../.plexupdate -U -U -U -U -U

force flag doesn't work with config file

sudo ./plexupdate.sh .plexupdate -f
Authenticating...OK
Finding download URL to download...OK
Your OS reports the latest version of Plex (1.0.1.2396-c094d0d) is already installed. Use -f to force download.

Autoinstall command for RPM-based distros

First, great script. :) Just a note that "rpm -i" should be "rpm -u" (to upgrade the RPM) for an auto-upgrade. Though, it's probably best to use "yum localinstall $RPM" instead so that it can decide the correct action and pull any dependencies too.

Progress Bar While Downloading

First of all I want to say I absolutely love you script. It has made updating Plex on my server a breeze.

I am wondering if it would be possible to add a progress bar when the PMS file is downloading?

systemd timer and service unit

Not an issue really, just thought i'd throw in a timer and service unit here. Do what you want with it. People also need to change the path and maybe user depending on how it's run.

/etc/systemd/system/plexupdate.service

[Unit]
Description=plexupdate
After=network.target

[Service]
ExecStart=/root/plexupdate/plexupdate.sh -a -c -d -p -s -u

/etc/systemd/system/plexupdate.timer

[Unit]
Description=Run the plex updater daily

[Timer]
OnCalendar=daily
Persistent=true     

[Install]
WantedBy=timers.target

systemctl daemon-reload
systemctl enable plexupdate.timer

Now bring the systemd hate and tell me it's simpler in cron! 😆 ng:

Can't upgrade, plexupdate thinks someone is using the server

plexupdate says my server is in use so it can't bother to AUTOINSTALL.

I confirm it is not in use.
plexupdate runs a wget to my PLEXSERVER, but the server is rejecting the request due to invalid credentials.

It could very well be because Home is setup; and if that's the case, maybe do a RESULTCODE for 401 and warn about Home; if it is Home, then I will just disable the check and do it live 👍 I'm unwilling to disable Home right now to confirm though.

I also found these when I was making the output more verbose, but probably resulted from making some commands more verbose.

Autoupdate recieves an error

When using the AUTOUPDATE functionality, setting AUTOUPDATE=yes I recieve the following error:

Auto updating...OK
plexupdate.sh: line 124: plexupdate.sh: command not found

I'm using Ubuntu 14.04 64bit.

Folder not empty error

When running the update, I would get cannot delete directory; not empty, when it tries to presumably replace the bundles with updated info. Is this normal?

Error: Download directory does not exist or is not a directory

Hi all,

I am having problems with the configuration - i have the download folder set as ~/Downloads (the folder does exist), however I'm getting the error message - "Error: Download directory does not exist or is not a directory"

Script doesn't work with PlexPass

Thanks for your script, very useful !

Trying to update with my login/pwd in script just downloads plexmediaserver_0.9.12.4.1192-9a47d21_amd64.deb while plexmediaserver_0.9.12.7 is available for plexpass users.

Detect current version to see if it needs an update

I'd love to see a basic function in the beginning that would check the web version against the current version to see if an update is needed.

CURRENTVER=export LD_LIBRARY_PATH=/usr/lib/plexmediaserver; /usr/lib/plexmediaserver/Plex\ Media\ Server --version | awk -F[v-] '{print($2)}' would give the numeric string of the version.

Error Installing 64-bit on ARM

The package (64-bit) downloaded fine, but returned "ERROR: dpkg: error processing /root/plexmediaserver_0.9.16.4.1911-ee6e505_amd64.deb"

Apparently, my server has an ARM processor and the dpkg didn't like it.

See here --> [img]http://i.imgur.com/S4PMZbV.png[/img]

Username and password verification not working

When grepping the raw data for 'Sign In</title' this will always not find it since that text string doesn't exist on the new website.

Better to search for 'Logout' to verify login success.

dpkg: warning: unable to delete old directory '/usr/lib/plexmediaserver/Resources/Plug-ins-a17e99e': Directory not empty

I get this error whenever I update using plexupdate.sh (obviously the hex value in the Plug-ins-a17e99e changes with each version.) I have a YouTube plugin that for some reason never seems to be moved when I perform an update. This is an Ubuntu PMS install and the permissions seem to match all the other plugins folders and I'm using sudo when running it.

I can manually go in an do something like:

sudo mv /usr/lib/plexmediaserver/Resources/Plug-ins-a17e99e/* /usr/lib/plexmediaserver/Resources/Plug-ins-c093d0d/

and it moves fine, I can then safely delete /usr/lib/plexmediaserver/Resources/Plug-ins-a17e99e

Since the error appears to be from dpkg, I'm not sure why some plugins seem to be moved while this youtube one doesn't. Any ideas?

I should mention that PMS is successfully updated, but since that YouTube plugin isn't moved over, it stops showing up under Channels after I update PMS (until I manually move it.)

Error when running script

I am on Ubuntu 14.04.2 when running the script with sudo sh plexupdate.sh i get:

Is there anything i can do?

Thanks

Force conf override

Ran the script with AUTOINSTALL=yes but got stuck waiting to replace plexmediaserver.conf

Configuration file '/etc/init/plexmediaserver.conf'
==> File on system created by you or by a script.
==> File also in package provided by package maintainer.

Perhaps

Script cannot run - /bin/bash^M: bad interpreter

When running the script, I get:
bash: ./plexupdate.sh: /bin/bash^M: bad interpreter: No such file or directory

I had to install package tofrodos and run the fromdos utility.
TIP: Don't write linux scripts on windows? :)

Eternal AutoUpdate

When the autoupdate option (-u) is used the script keeps looking for updates in loop forever.

Error when having $ (dollar sign) in password

Hello!

I am getting Error: Username and/or password incorrect when using your script.
My password has all the crazy characters in it ($, @, &, !, %), so I did some testing and it seems like the URL encode (?) can't handle $ (dollar signs), because when I remove that it works perfectly.

A quick fix for me would be to remove the dollar signs from my password, but I am wondering if there is any other way to do it

Ubuntu 14.10 (Linux server 3.16.0-43-generic)

Authenticating...Error: Unable to obtain authentication token, page changed?

So after the script has been running fine for like the last month this is suddenly happening. The login page didn't change as suggested though. Any ideas?

Error since upgrading Ubuntu 15.04 (support for Ubuntu 15.04)

First to say, that this script is awesome and it makes plex on linux so much easier, thanks

I have updated my Linux server updated to Ubuntu 15.04.
I understand that Canonical changed the boot and service management.
And when running the script, im getting errors

Readme issues

I tried following the guide and found a few issues. Everything is working now but it may help for those in the future who try installing it.

In 2. setting it up you have it set to email and pass, but in TL;DR, you have user and pass. User and pass wont work if the user has the only accept email option enabled.

Second thing, wget https://github.com/mrworf/plexupdate/blob/master/plexupdate.sh downloads the html page, not the actual code.

https://raw.githubusercontent.com/mrworf/plexupdate/master/plexupdate.sh would be the right link instead.

Doesn't produce expected result on CentOS

Thanks for a great script, however there are other distributions besides Ubuntu, yet it still downloads the deb-file when ran on CentOS.

Unfortunately just replacing .deb with .rpm didn't work as the naming convention is slightly different for CentOS/RHEL and my sed-mojo is not strong enough to overcome the problem.

Here's what I get when replacing .deb with .rpm:

Reinstall plugins after update

It would be nice if plugins are moved to the new directory plugin directory, or reinstalled from a git repository.

There is also a exit 2 as the return status.

The AUTOSTART exit 2 should likely be a function of either AUTOINSTALL or AUTOUPDATE set to "yes" instead.
Basically creates the option for using this script as a cron checker for updates that only notifies when there is an update.

Thanks

Cron mode doesn't really make sense

I'm struggling to understand what scenario -c is actually meant for.

Every cron implementation I've used just ignores exit codes completely, so -c would seem to have nothing at all to do with "cron". It looks like it was mostly meant to reconcile what @hakong wanted in #62 (which doesn't seem directly cron related to me) vs #73.

What I'm wanting to accomplish (without adding yet another command line option) is just a cron mode that only produces output when something has changed. If you have the latest version, no output. If you don't have the latest version, produce output on STDOUT. If there's an error (regardless of if there's a new version or not) produce output on STDERR.

This way, -q and -S actually become useful modifiers to -c, whereas they currently largely replace it. (running with -cq is functionally identical to running with -q inside cron).

I'm happy to send in a PR for this functionality, I just wanted to bring this up ahead of time to make sure that I'm not stepping on any toes by doing so (or missing something obvious).

Looks for configuration in wrong directory

Running as superuser is required to actually install updates in CentOS, but when this is done the script looks in the home directory of root rather than of the current user.

Says its on latest version. Plex says an update exists

I created the .plexupdate file with my login/passwd for plex.tv but seems like it keeps trying public deb package and not plex pass version.

broken now with new site layout

The new site layout seems to have broken everything, not really unexpected though.

KEEP doesn't do anything

It looks like KEEP has been rendered useless since 170db36. Since /tmp/kaka is deleted on exit, there's really no option to keep your session anymore. I personally don't care all that much, so just removing it altogether would work. If you want to have it work I'm happy to send in a PR since I've already dug into the code to see why it's not working in the first place.

dpkg interrupts update installer if Plex config file is changed

I would like to update Plex automatically on my Ubuntu server 14.04 from cron so for that your script comes in perfectly.

However I edited Plex' config file (/etc/default/plexmediaserver) to run Plex as a different user and that results in dpkg interrupting the installation process.

I ran your script as:

$ sudo plexupdate.sh -a -d -p -u

And I get the following message from dpkg:

Configuration file '/etc/default/plexmediaserver'
 ==> Modified (by you or by a script) since installation.
 ==> Package distributor has shipped an updated version.
   What would you like to do about it ?  Your options are:
    Y or I  : install the package maintainer's version
    N or O  : keep your currently-installed version
      D     : show the differences between the versions
      Z     : start a shell to examine the situation
 The default action is to keep your current version.
*** plexmediaserver (Y/I/N/O/D/Z) [default=N] ?

I looked through the dpkg command line options hoping I could add one on line 333 of your script as to automatically skip the manual confirmation but I didn't find anything useful.

Is it possible for you to update the script so fully unattended Plex updates are possible in my situation as well? Or can you give me recommendations for it?

Thanks!
