Linux install complains of absent intel opencl libraries when latest/later versions already installed

[prosewall]

Server Version#:linux-x64-1.27.0.5849
Player Version#:
ubuntu jammy jellyfish x65 install
Intel Alder-lake cpu/gpu
intel opencl installed. From main repository have later versions that those reported to be required by the plex media server install.
See below apt output and listing of already installed intel opencl - complains they are not installed and requests earlier versions from intel store to be installed - attempting complains that those versions are outdated, and newer versions already exist.

Plex Media Server is incompatible with Intel Compute Runtime after 21.49. Intel changed the API after 21.49. Plex Engineering is working to make PMS compatible with the new API.

You’ll need to uninstall the current versions and install ICR 21.49.

You should also mark each package so it will not auto-update: sudo apt-mark hold pkg_name

Future versions of PMS will mark the packages automatically. Additional details: Ubuntu 22.04 Packaging - development & preview.

[ChuckPa]

To add to FordGuy61,

I’ve since made a few final refinements to the package he pointed to.
(My forum development / preview thread).

Unless errors are uncovered, I will submit what’s available there to QA for release as PMS production.

[prosewall]

Thank you, that resolved the situation for the warnings from the plex installer, but I’m now concerned as to how this will impact other applications long term, and how will I know when to remove the upgrade block if and when Plex supports the later API.?

[FordGuy61]

@prosewall

how will I know when to remove the upgrade block if and when Plex supports the later API.?

Any such update will appear in the beta builds first.

Watch the release announcements for Plex Media Server and the “What’s New” notification in Settings → Server_Name → General when a new build is available.

Also, there will most likely be a lot of traffic on the forum in the server-linux section.

[ChuckPa]

@prosewall

, and how will I know when to remove the upgrade block if and when Plex supports the later API.?

When engineering makes the changes available, the package will automatically manage the ‘unhold’ action for the ICR modules.

[prosewall]

After installing the updates available through the beta channel, the glibc libraries the opencl depends upon get unreserved and released and require manual reinstallation to reenable plex opencl libaries to be correctly detected. the alternate libraries that are removed upon upgrade are
libclang-cpp12 libigc1 libigdfcl1 libllvm12 libllvmspirvlib12 libopencl-clang12
which the intel opencl package appears to need to allow plex to use the library, however the beta reinstalls the same intel opencl package and it does not have those dependencies in it apparently. OpenCL libarary detection fails until they are reinstated, even if the correct versions of the intel libraries are installed and a hold places upon them.
