Sudo apt-get upgrade returning with error

Device : Jetson Nano 4GB
Jetpack: 4.4.1

I have download the archived version of jetson nano which had jetpack 4.4.1, and burned the SD card, after that did

sudo apt-get update

which worked with no issue but then doing

sudo apt-get upgrade

gives this error:

Errors were encountered while processing:
E: Sub-process /usr/bin/dpkg returned an error code (1)

Even tried the image with jetpack 4.4 but same issue.
Tried burning the same image multiple times but still same.

Downloaded the archive images from here :JetPack Archive | NVIDIA Developer


hello priyanshthakore,

for example, $ apt list --upgradable

Running that command this is the result i get nothing else.

hello priyanshthakore,

so all packages were already updated?
please compare the md5sums within dpkg, for example, $ cat /var/lib/dpkg/info/nvidia-l4t-bootloader.md5sums

This is the full output of sudo apt-get upgrade

All packages seems to be upgraded but just this once returns with and error, will removing it affect functioning of jetson ? through

sudo apt-get --force-yes remove nvidia-l4t-bootloader

hello priyanshthakore,

sorry, you may simply use this command, $ dpkg -l | grep bootloader to check the package version.

please also gather logs for reference,
i.e. $ cat /opt/ota_package/bl_update_payload.log
could you please also check the TNSPEC as following,
i.e. $ cat /etc/nv_boot_control.conf

hello priyanshthakore,

please check this, thanks
