Server Version#: 1.21.0.3616 OS: Debian Unstable I’m getting consistent errors when upgrading Plex. apt will start throwing errors after Plex is installed and the errors are consistent until I remove /var/lib/dpkg/info/plexmediaserver.postinst. apt will continue to throw the error on regular system updates until I remove the file mentioned above. I’m forcing Plex to run under my user account and have a custom database directory. I think Plex’ postinstall script for Debian-based distributions needs a little help. edit: beignet error in apt log isn’t a finding. Media server is a first-gen i7 laptop and beignet is only for 3rd gen and later. apt log: > Preparing to unpack …/plexmediaserver\_1.21.0.3616-d87012962\_amd64.deb … > PlexMediaServer install: Pre-installation Validation. > PlexMediaServer install: Pre-installation Validation complete. > Unpacking plexmediaserver (1.21.0.3616-d87012962) over (1.20.5.3600-47c0d9038) … > Setting up libdouble-conversion3:amd64 (3.1.5-6.1) … > Setting up plexmediaserver (1.21.0.3616-d87012962) … > PlexMediaServer install: PlexMediaServer-1.21.0.3616-d87012962 - Installation starting. > PlexMediaServer install: > PlexMediaServer install: Now installing based on: > PlexMediaServer install: Installation Type: Update > PlexMediaServer install: Process Control: systemd > PlexMediaServer install: Plex User: wizard > PlexMediaServer install: Plex Group: wizard > PlexMediaServer install: Video Group: render > PlexMediaServer install: Metadata Dir: /media/external/plex/Library/Application Support > PlexMediaServer install: Temp Directory: /media/external/temp (set in Preferences.xml) > PlexMediaServer install: Lang Encoding: en\_US.UTF-8 > PlexMediaServer install: Config file used: /etc/systemd/system/plexmediaserver.service.d/override.conf > PlexMediaServer install: Intel QSV Hardware: Not found > PlexMediaServer install: > PlexMediaServer install: OpenCL library: Installed > PlexMediaServer install: Beignet package: Not Installed > PlexMediaServer install: > PlexMediaServer install: WARNING: Package ‘Beignet’, required for hardware transcoding of HDR content, is missing. > PlexMediaServer install: Please install package: ‘beignet-opencl-icd’ > PlexMediaServer install: > PlexMediaServer install: Completing final configuration. > /bin/mkdir: cannot create directory ‘/var/lib/plexmediaserver’: File exists > dpkg: error processing package plexmediaserver (–configure): > installed plexmediaserver package post-installation script subprocess returned error exit status 1 and here’s my /etc/systemd/system/plexmediaserver.service.d/override.conf: > [Service] > Environment=“PLEX\_MEDIA\_SERVER\_APPLICATION\_SUPPORT\_DIR=/media/external/plex/Library/Application Support” > User=wizard > Group=wizard ---

Plex updates successfully but since the plexmediaserver.postinst is failing it throws an error any time you run updates in apt or aptitude and interferes with another apt tool called “needrestart” which tells me which services need restarting and which applications have stale binaries. if dpkg closes with an error needrestart will not run, so I have to remove /var/lib/dpkg/info/plexmediaserver.postinst to get apt working correctly again. This makes sense? cheers - ---

I am sorry but I’m not going to try and hit a moving target. It is working for everyone else. Besides, I am sufficiently unstable myself without working on a distro under development 🤣 ---

I recently tried to upgrade to plexmediaserver\_1.21.0.3711 with dpkg and something failed in the post installation. As a result, there is a lock preventing apt from running. This is on Ubuntu 20.04. Is there some information that will tell us if this is the same problem or a new problem? ---

@rbrown Can you shed some more information please? 1. Was the normal update service running when you attempted to install? It holds the same lock file as `dpkg` to prevent corruption of the dkpg database. 2. Were you `root` at the time? ---

1. I am not sure I know how to check the answer to the first question. Are you referring to the unattended-upgrades service? According to the logs, this service ran at 6.17am on 12/3 while the upgrade with dpkg was run at 10:28 am on 12/3. 2. The upgrade of plex was carried out with the command `sudo dpkg -i plexmediaserver_1.21.0.3711-b509cc236_amd64.deb` so yes, it was executed as root. Since my original post, I killed the dpkg process, removed the lock file /var/lib/dpkg/lock-frontend and ran `sudo dpkg --configure -a`. This ran and afterwards I will able to use apt to carry out upgrades. ---

@rbrown Thanks for detailing. Something/somehow your dpkg left itself in a locked state. I never understood how that can happen but it does. If everything cleared through and it didn’t specifically call out the Plex DEB file then we’re good. You can install the existing on top of what’s already there as a double-check if you like to make sure it’s in a known-good state. ---
