Hi guys,
I installed the plexmediaserver via the official repo. Now i want update the server, but it exit with the error code (1) in the “pre-installation”.
E:Sub-process /usr/bin/dpkg returned an error code (1)
i have download the pakcage 1.21. and i want to install with
sudo dpkg -i plex...deb
and i get the same error.
How can i fix the problem?
Is your Raspbian / Raspberry Pi OS up-to-date?
Jep. I do a full
apt-get update
apt-get upgrade
Plexmediaserver is in the /etc/apt/sources.list.d/plexmediaserver.list
deb https://downloads.plex.tv/repo/deb public main
I also downloaded the deb-packet and try to install.
Is there any other useful output from the apt install command?
Please try to uninstall your current package and then reinstall the new one. Don’t worry, your whole setup will remain intact. Just do not use the purge option.
sudo apt remove plexmediaserver followed by your manual sudo apt install ./plex...deb
no luck…
remove is no problem, but install…

That’s a strange output. Have you disabled system logs on your Pi?
Btw: did you try turning it off and on again? 
I dont think so.
Syslog is enable…
It was actually the syslog or systemd journald.
systemctl restart systemd-journald.socket
systemctl restart systemd-journald.service
after that, i can install pms with
apt-get install plexmediaserver
It returns warnings but installation is complet!
