Like the title states, i have installed blender on linux and everything works fine, except for the OpenImageDenoise, i am sure that my computer does support that feature as when i use blender on windows it works fine, why does it not work on the linux version? The node is there but it just says "disabled, built without openimagedenoise"
In my case, I was getting this error on Ubuntu. I went to the Ubuntu Software app and realized there were two Blender packages, and the one I had installed was from the ubuntu-groovy-universe source, which was on an old version. Use the one from the snapcraft.io source. Switching made this work for me.
