Stuck on Getting Started with Jetson AGX Orin Developer Kit course

I was able to get past step 1 just fine, but I’m stuck at step 2; it says that, to install the JetPack components, I have to run those four commands in the terminal, but whenever I try to run any of them, it asks me to input my password, but nothing happens when I try to type it in. I can’t figure out how to get around this; someone please help!

Hi

Did you make sure your board has internet access?

Do you see any message after typing your password? It should looks like this:

nvidia@ubuntu:~$ sudo apt update
[sudo] password for nvidia:

Yes my board does have internet access; when I first booted it up, it had me connect it to WiFi. And when I open a terminal, I first type in a command, at which point it asks for a password, but nothing happens when I try to type; no matter which key I type, nothing happens. I have no idea what I’m doing wrong.

Hi,

Could you access your device using ssh?

Thanks

What is SSH?

sudo apt update
[sudo] password for your_userid:

sudo then waits for you type the password, it just doesn’t show your password to you as a security measure.
Type your correct password and press enter.

Then it will say
variable_number packages can be upgraded.

Then you type:
sudo apt upgrade

the apt application will then prompt you to type y or n

type y

hit enter
Then apt will install the upgrades.

Just about every program you can access from the command line will provide brief explanation when you type
program_name --help

So if you were to type, for example:

apt --help
or
ls --help

The program will show you command line options and how to use the command.
