Hi,

Could you check if there is already a folder named “Linux_for_Tegra” under your installation path?

If so, could you go into there, put your device to recovery mode and then use command

sudo ./flash jetson-xavier mmcblk0p1

You’re missing the older Python (and possibly others). Try:

sudo apt-get install libgconf-2-4 libcanberra-gtk-module
sudo apt-get install python

(python2 gets installed, whereas only python3 is there by default)

From logs:
