How to upgrade jetpack without to flash the nano

Hello to everyone.

I see that the jetpack 4.5 is out. I would like to know how can I upgrade my jetpack (vers. 4.4) to version 5 without to reflash the board. I’ve tried using the apt system on ubuntu,giving this command :

apt install nvidia-jetpack

but I see that it doesn’t install the version 4.5,but it is freezed on version 4.4.1-b50. Is there another method to upgrade it instead of reflashing it ? I have also gave a look at the SDK manager,but it seems that it can only flash the board,destroying everything and I don’t like it.

this is my /etc/apt/sources.list. is missing some repository ?

The “sources.list” is not the right place to look at.

Actually I’m Follow the instructions of the “To upgrade to a new minor release” section from here:

https://docs.nvidia.com/jetson/l4t/index.html#page/Tegra%20Linux%20Driver%20Package%20Development%20Guide/updating_jetson_and_host.html

This should perform the update to Jet Pack 4.5,BUT it didn’t. This is what happens when I enable these repos and I do apt upgrade :

N: “main / binary-armhf / Packages” file acquisition skipped as the repository “https://repo.download.nvidia.com/jetson/common r32.4 InRelease” does not support the “armhf” architecture

N: “main / binary-armhf / Packages” file acquisition skipped as the repository “https://repo.download.nvidia.com/jetson/t210 r32.4 InRelease” does not support the “armhf” architecture

root @ ziomario-desktop: ~ # apt upgrade

Reading package list …

Done Dependency tree generation

Read status information … Done Calculating the update … Done 0 updated, 0 installed, 0 to be removed and 0 not updated.

this seems to be the fix :

anyway I can’t do that,I can’t purge the armhf libs like this :

sudo apt-get purge ".*:armhf" 
sudo dpkg --remove-architecture armhf

because I'm running some important armhf applications on the nano,such as :
