Hi, there:
I’m new to Jetson AGX Xavier and I’m following tutorials to download Jetson OS and Jetson SDK Component using SDK Manager. However, it seems I could not finish downloading Jetson OS image and CUDA toolkit for L4T no matter how many times I tried. Here is the related log:

I believe it should be some problem with my internet connection. Are there any stand alone links for these files?

Hi aldaris,
There is no direct links to the download files. You could look up the ~/.nvsdkm/dist/sdkml3\_jetpack\_l4t\_441.json file, find out all lines start with “url”, for example,
` "url": "cuda-repo-l4t-10-2-local-10.2.89_1.0-1_arm64.deb"`
Then concatenate the url with [https://developer.nvidia.com/assets/embedded/secure/tools/files/jetpack-sdks/jetpack-4.4.1/JETPACK\_441\_b50/](https://developer.nvidia.com/assets/embedded/secure/tools/files/jetpack-sdks/jetpack-4.4.1/JETPACK_441_b50/)
Take above url as an example, we can get
[https://developer.nvidia.com/assets/embedded/secure/tools/files/jetpack-sdks/jetpack-4.4.1/JETPACK\_441\_b50/cuda-repo-l4t-10-2-local-10.2.89\_1.0-1\_arm64.deb](https://developer.nvidia.com/assets/embedded/secure/tools/files/jetpack-sdks/jetpack-4.4.1/JETPACK_441_b50/cuda-repo-l4t-10-2-local-10.2.89_1.0-1_arm64.deb)

Thank you very much, Edward. Just realize how stupid my question is.
