[Clearpath Husky] | nvidia board | can't Install software

Software
1

Hello,
I can’t update or install any software because of some unmet dependencies:

You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
 nvidia-l4t-jetsonpower-gui-tools : Depends: nvidia-l4t-core (= 35.2.1-20230124153320) but 35.2.1-20230121191456 is installed
 nvidia-l4t-nvfancontrol : Depends: nvidia-l4t-core (= 35.2.1-20230124153320) but 35.2.1-20230121191456 is installed

E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

Whe I try the suggested fix with sudo apt --fix-broken install, the output looks like this:

 debconf: delaying package configuration, since apt-utils is not installed
(Reading database ... 239143 files and directories currently installed.)
Preparing to unpack .../nvidia-l4t-core_35.2.1-20230124153320_arm64.deb ...

Can someone help me?

Dear @szik,

This issue is independent of the Husky and is of Nvidia exclusively.

As mentioned by Nvidia in their forums. One should not try to upgrade the Nvidia as it has a special distribution and upgrading via the sudo apt-get upgrade can brick the system or damage the software components. Also, the sudo apt-get update for Nvidia specifically has a certain procedure.

Provided that your Nvidia is working without issues, I would advise to ignore these warnings.

Thanks for the reply Sohail,

I can’t really ignore it, because I can’t install any software on it now. Is there a way to fix it? do I have to reset the whole thing to factory settings?

Could you post the error when you try and install a package?

Could you please tell me which Nvidia (Orin or Nano) you have, which ROS distribution is being used, and which sensors are active, perhaps I may have a clone of it!

Also, there is a long round about solutions for this which may or may not work, however, the fastest way would be to flash the Nvidia with the jetpack installer.

I would suggest to backup:

  • ros workspace (if available)
  • .bashrc
  • /etc/udev/rules.d/* (the exclusive rules for some of the sensors if available)
7

Please note if you can install other items (e.g. sudo apt-get install terminator or something), it may be currently that this application is not supported in this version, in which case I advise against flashing it and seeking an alternative way of installation!

8
  • ROS: Foxy
  • no sensors currently running, generally ZED2i camera and Livox Lidar attached
  • How do I know which Nvidia I have?

If I need to flash it, is this the right instruction for that?

9

Correct, for checking nvidia version use:

cat /etc/nv_tegra_release

Also, please check if you install other applications or is only this application.

10

nv_tegra_release:

> cat /etc/nv_tegra_release 
# R35 (release), REVISION: 2.1, GCID: 32398013, BOARD: t186ref, EABI: aarch64, DATE: Sun Jan 22 03:18:23 UTC 2023

installing anything else results in same error:

> sudo apt-get install terminator
[sudo] password for administrator:

terminator is already the newest version (1.91-4ubuntu1).

Seems to me a NVIDIA Nano B01 and most probably Ubuntu 18.04

12

Terminator is already installed and its showing successful, please try with some other package.

13

It should be Ubuntu 20.04, here are the details.

oh yea, didn’t check… you guys must have installed it, while setup. Here is something else:

same result.

Could you try running this command:

sudo apt install nvidia-l4t-openwfd nvidia-l4t-vulkan-sc-dev nvidia-l4t-vulkan-sc-samples nvidia-l4t-vulkan-sc-sdk nvidia-l4t-vulkan-sc nvidia-l4t-jetsonpower-gui-tools

Also, I have checked, we have the ros_ws backup available for your workspace.

Unfortunately this doesn’t work either:

So I can use Jetpack to flash this back to the original settings?

18

Yes, either you can directly backup the ros_ws and flash, as well as rebuild the ros workspace.
