I can't install jetpack 4.2 sdk on my tx2

Manually run “sudo ifconfig 192.168.55.100”, make sure you can ssh connect to 192.168.55.1 with this ethernet port.

so net tools isn’t installed by default on 18.04 so i installed that.
then i ran the above cmd and i get “usb-thernet-port: no such file or directory”

then i thought that maybe refers to the interface name, so i tried u-e-p without the <> and i also tried l4tbr0 and both options gave me " SIOCSIFADDR: No such device"

what else should i try ?

@edward sorry your posts aren’t helping me… it’s getting really frustrating. The flash is failing on the scp command per previous logs uploaded. It’s not getting past there … can you please provide an example netplan configuration for Ubuntu 18.04.2 LTS… or arrange for the appropriate skilled person in Nvidia to do so

Hi aschofield,
The should be replaced by the actual usb-ethernet port name on your host machine (PC, not jetson device). On different host machine, the port name varies. For example, on my machine, its name is “usb0” or “usb1”; on other people’s machine, it may be “enp0s20u1i5” or something else. You could try to unplug then plug the usb cable, and use “ip addr” command on HOST machine to compare what port names are changed, to find out the actual usb-thernet port name on your machine.

@edward we need a Netplan configuration example please … you’ve been describing things for Ubuntu 16.04 not Ubuntu 18.04… I mentioned previously how networking is configured has changed between releases

nick,
The scp error you saw before flashing can be safely ignored. Please make sure you can manually flash the Jetson device first. https://devtalk.nvidia.com/default/topic/1048660/jetson-tx2/i-can-t-install-jetpack-4-2-sdk-on-my-tx2/post/5327769/#5327769
If manually flashing also fails, you may need change a usb cable or usb port to see whether it solved your issue.

Hi Edward,

Its as though the host machine is not seeing the TX-2 via usb as a network device.

If i do a dmesg | grep “usb#” where the # is 1 through to 10 i do not get any nvidia device.
I only get a xHCI host controller or EHCI host controller.
I have looked through dmesg and cannot find a usb network device.

Is there another way we can install the sdk components on the TX-2 ? via apt ?

Hi aschofield,
On some machine, the usb-ethernet port name may not contain any “usb”, such as “enp0s20u1i5”. You can find out the port name with below steps:

  1. Power on Jetson device, make sure it is started up and you can see Ubuntu desktop in HDMI output.
  2. Make sure usb cable is NOT connected between Jetson device and host.
  3. Run “ip addr” command in terminal on HOST machine.
  4. Connect usb cable between host and Jetson device.
  5. Run “ip addr” command in terminal on HOST machine again.
  6. Compare the difference of the output between step 3 and step 5. The expected result is that in step 5, “ip addr” command should list two additional ports than in step 3. Either port can be used as name.

@edward we’ve been over and over and over this …, you are missing something fundamentally in your understanding where people are stuck. Please escalate so we can get this fixed. There is a real problem with the Nvidia software. Thank you

Done. both before usb connection and after only show eno1 (ethernet connection) and lo (loopback) in the network interfaces.
I tried ifconfig and ip addr.

The issue is that Ubuntu 18.04.2 LTS does not install the USB NETWORK.

I will downgrade my laptop to 16.04 LTS and try jetpack 4.2 and see if that works but from memory yesterday, 4.2 is not compatible with Ubuntu 16 anymore…

Please escalate and advise.

Hi aschofield,
JetPack 4.2 is compatible with both Ubuntu 16.04 and 18.04 host. So no need to downgrade or upgrade if you are already using one of them. May I ask if you are using Ubuntu 18.04 Desktop image or Server install image (see Ubuntu 18.04.6 LTS (Bionic Beaver))?

It was a fresh install using ubuntu-18.04.2-desktop-amd64.iso

@edward JetPack 4.2 does not work on Ubuntu hosts 18.04.2 as we’ve all been trying to tell you … please escalate … some people appear to have got it working after playing around with network settings or out of luck or fudging things. For what should be a simple task, there are a lot of people, that have wasted a lot of time trying to install JetPack 4.2 on their tx2s

In this thread, there are multiple different issues mixed, and it is very difficult to track, investigate, and solve these different issues. We’d better lock this thread. And for different type of issues, please open a new thread with specific issue you have. Please provide complete information in the new thread. For example, host environment, Jetson device type, installation fails at which step, and the full log.

Hi Edward,

From what I can we we have multiple users with the same issue. We are both on Ubuntu 18.04.2 LTS and we both do not have any USB network interface on our host machine.

Please advise
