Plex does not officially provide an APT repo yet although it is planned. For ARM devices there is currently a 3rd party repo available that was even necessary since Plex did not offer official ARM packages. But now with v1.15 ARM packages have been added and the maintainer of the 3rd party repo (dev2day) already announced that the repo will be shut down in some weeks.
As said Plex plans an own repo then but since this would be available publicly most likely no Plax Pass versions will be shipped there. So if there is no internal updater available you would still need to download them manually.
We currently ship the official packages with fresh installs and will switch to the official repo once available but for Plex Pass versions I see no way that we can automate this currently.
PMS v1.15.3 is in the public update channel now, I have installed it on my desktop already (I am not a Plex Pass owner). How I proceed with installing it on my DietPi box? Just downloading the package manually and using dpkg command to install it? What is the best strategy for uninstalling previous version, the one packaged by dev2day? I do not want to lose my Plex database in the process.
Can you share how you updated it? Im bit new in linux trying to update PMS because iOS device cant play files from web client. And on new WebClient this bug is fixed, but when I open from other device my plex webclient I get old version…
I believe the actual name of the (old) repository source file you will need to remove is “/etc/apt/sources.list.d/plex.list” and NOT “/etc/apt/sources.list.d/pms.list”, as the example suggests. Other than that, the instructions worked fine for me.
