Can I update from JP4.4 DP to JP4.4 safely via apt?

After the fiasco to update from JP4.4 DP to JP4.4 that made me stop working on Xavier NX, is it possible upgrade safely already?

Other question, is it possible install OpenCV 4.3/4.4 Contrib with CuDNN, CUDA (the one in JP4.4, I think is CUDA10), and fully supported by TensorRT and DS4? I remember a member told OpenCV 4.3 was broken.

And last one, Jetpack 4.4DP is asking update to Ubuntu 20.04, can I do it?

Thanks

Hi fpsychosis,

Suggest you can use sdkmanager to install the latest JetPack-4.4.1.

You also can use below steps to upgrade your system to the latest JetPack:
$ sudo apt update
$ sudo vim /etc/apt/sources.list.d/nvidia-l4t-apt-source.list
       deb https://repo.download.nvidia.com/jetson/common r32.4 main
       deb https://repo.download.nvidia.com/jetson/t194 r32.4 main
$ sudo apt update
$ sudo apt upgrade
$ sudo apt install nvidia-jetpack
