How to set proxy DRIVE AGX?

Hardware Platform: [DRIVE AGX Pegasus™ Developer Kit]
Software Version: [DRIVE Software 10]
Host Machine Version: [native Ubuntu 18.04]
SDK Manager Version: [1.2]

After Flashing and entered the OS, I find the settings->network is unavailable.
[NetworkManager needs to be running] is shown in the Network setting window.
Is it normal thing?
If I want to add proxy settings, what should I do?

I have set HTTP_PROXY and HTTPS_PROXY in ~/.bashrc and /etc/apt/apt.conf,
but still get errors as following.

What else should I do?

nvidia@tegra-ubuntu:~$ sudo apt-get update

Hi @Liang_Qi,

Please refer to below post from a developer sharing his experience in DRIVE Software 10.0 and see if helps.

Also we would like to know if you’re able to ping XA & XB from your x86 host system.

You can also check NetworkManager.service status with below command.
$ sudo systemctl status NetworkManager.service

Dear @Liang_Qi,
Any update can be provided?

Thanks for sharing the link, it is useful and I solved my problem by Clock setting.

Thanks for letting us know your problem was solved!

Do you mean clock setting solving your “sudo apt-get update” problem?
