Try ‘apt --fix-broken install’ with no packages (or specify a solution).

I tried many things on the forums but none work. Is the cuda verison 11.5 good for the Xaiver AGX or should i specify another version Thank You ---

FYI, this is the Nano forum, you should probably use the [Xavier AGX](https://forums.developer.nvidia.com/c/agx-autonomous-machines/jetson-embedded-systems/jetson-agx-xavier/75) forum. You cannot use the desktop PC version of the driver for discrete GPUs (dGPU). These were designed for PCI devices, but the GPU in a Jetson is integrated directly to the memory controller (iGPU). Details such as “nvidia-smi” are only available for PCI-based dGPUs. The only place you should get CUDA from is JetPack/SDK Manager. This has the correct release of the correct driver for the version of L4T that is flashed to the Jetson. I am guessing you’ll have to flash the system again. ---
