Hi, At the end of installation, I got the following errors(1). As asked, I tried to install manually CUDA on Xavier but it didn’t work(2). I notice that Xavier is an ‘aarch64 GNU/Linux architecture’ and I couldn’t find this kind of package. Could you tell me how to resolve these issues, please. Thanks in advance.

Just re-flash the device with the JetPack. Make sure to select “install cuda” among the target-installable libraries in the GUI. ---

Thanks a lot for your reply. As noted in the following errors, I just realized that my Xavier Device is not correctly connected to wifi network. Err:3 [Index of /ubuntu-ports](http://ports.ubuntu.com/ubuntu-ports) bionic InRelease Could not resolve ‘[ports.ubuntu.com](http://ports.ubuntu.com)’ ---

You need to connect using wired Ethernet for the Jetpack installation to work. ---

Yes, I did. My Xavier Device is flashed, now. Thanks a lot for your help.
