If we use Jetson Nano's default image to start our project, we may have some follow steps to make our work easier.

Fix a config

Bash
sudo chown root:root / /lib

Clean up desktop packages

Bash
sudo apt purge ubuntu-desktop -y
sudo apt-get remove -y nautilus nautilus-* \
    gnome-control-center gnome-screenshot gnome-power-manager \
    gnome-screensaver  gnome-bluetooth gnome-shell-common \
    gnome-termina* gnome-pane* gnome-applet* gnome-desktop* \
    gnome-sessio* gnome-user* \
    zeitgeist-core libzeitgeist* 
sudo apt-get -y autoremove

After that, try this:

Install jtop

Bash
pip install jetson-stats

Update ca-certificates

Bash

You may also use

sudo apt update
sudo apt install -y libgnutls30

instead.
