Unable to install Jetpack on Orin Nano with disk encryption

Hi.
I was trying to install Jetpack on my Orin Nano, that I flashed with commands from here. But after flashing I’ve got errors after trying to run sudo apt update. SDKManager can’t install runtime components either. Attaching logs:

However, if I’m flashing with SDKManager there is no problem with updating and installing. What could be the reason of this behavior?

Fixed with changing file /etc/apt/sources.list.d/nvidia-l4t-apt-source.list from

deb https://repo.download.nvidia.com/jetson/common r35.4 main
deb https://repo.download.nvidia.com/jetson/t234 r35.4 main

to

deb [trusted=yes] https://repo.download.nvidia.com/jetson/common r35.4 main
deb [trusted=yes] https://repo.download.nvidia.com/jetson/t234 r35.4 main

Glad to know you found the solution, thanks for the sharing.
