Hi _av,

Are you using the devkit or custom board?
How did you flash the board?

@Andrey1984

sudo apt upgrade -y

Are you running this upgrade command on the board?

Please try the following command to check if it could help

$ sudo apt --fix-broken install

[Andrey1984]

resolved by reflashing
command above wouldn’t work

I am seeing the same problem repeatedly, even after reflashing with Jetpack 5.0.2.

It seems to be consistently happening after performing: sudo apt install nvidia-jetpack

Subsequent sudo apt upgrade commands have the same error as the OP suggested.

The package manager recommends sudo apt --fix-broken install

This tries to upgrade the following suspect packages:
The following additional packages will be installed: nvidia-l4t-nvpmodel The following packages will be upgraded: nvidia-l4t-nvpmodel

However this fails with the following error
E: Sub-process /usr/bin/dpkg received a segmentation fault.

Any subsequent use of apt appears to be broken, for example: sudo apt install nano has the same error as OP.

Any suggestions for a way forward here? I am using a devkit

Hi chh,

How did you flash the devkit?
Are you using standalone Ubuntu 18.04 as your host PC?
It looks like another issue as here, please file another topic to clarify.
