When will Orin Nano come out with a 22.04 system?
JetPack 5.x is Ubuntu 20, and the last I heard is that JetPack 6.x is going to be out near the end of this month. Presumably this would be based on Ubuntu 22 (it is called L4T, “Linux for Tegra”, but it is just Ubuntu plus NVIDIA drivers; there may be some new features in JetPack 6 which adds flexibility to this though). I don’t know of any “official” scheduled release for JetPack 6, but it would probably be called L4T R36.x when it comes out (maybe R37.x?). Orin would be supported for this, but not Xavier or earlier.
Thanks @linuxdev, yes JetPack 6 is supposed to be released at the end of this month (or early December) for Orin devices and it has Ubuntu 22.04.
