Jetpack 4.2: Run command "sudo ./" error

I am trying to flash latest Jetpack 4.2 to the xavier. When I run the command “sudo ./”. The following error occurs:

Using rootfs directory of: /home/etdjj/prj/xavier/32.1_L4T/Linux_for_Tegra/rootfs
Extracting the NVIDIA user space components to /home/etdjj/prj/xavier/32.1_L4T/Linux_for_Tegra/rootfs
tar (child): lbzip2: Cannot exec: No such file or directory
tar (child): Error is not recoverable: exiting now
tar: Child returned status 2
tar: Error is not recoverable: exiting now

But I do have the “bzip2” in my ubuntu system.

Hi zhuce_cgf,

Are you download root file system?

sudo tar xpf JAX-TX2-Jetson_Linux_R32.1.0_aarch64.tbz2
cd Linux_for_Tegra/rootfs/
sudo tar xpf ../../JAX-TX2-Tegra_Linux_Sample-Root-Filesystem_R32.1.0_aarch64.tbz2
cd ..
sudo ./
sudo ./ jetson-xavier mmcblk0p1

Download link:

I have downloaded the root file system. Actually the error is “tar (child): lbzip2: Cannot exec: No such file or directory”.
For now, I replace the “” with the old one in 31.1 to do the next step(

Hi zhuce_cgf,

I don’t hit this issue.
Suggest you can download the drive package and root file system again.

I have not yet used JetPack4.2 because my tiny laptop with Ubuntu is 14.04 (try not to laugh too hard, it is a dual atom), but I do notice libbzip2 is not available as part of the general operating system on what I have available. However, libbzip2 is present as part of gnome even on some older systems (it isn’t a part of the general linker path…this would be called only from specific gnome components if it is what I think it is). Are you using an alternative non-gnome Ubuntu 18.04?

I’m using Ubuntu 16.04 with gnome. And as I posted, bzip2 is already the newest version (1.0.6-8).

I don’t think it’s problem of drive package and root file system. Can you tell me the system version you are using? Thanks.

Hi zhuce_cgf,

My host system is Ubuntu 16.04
We are support Ubuntu Linux x64 Version 18.04 or 16.04


FYI, it isn’t bzip2 which it is missing…it is libbzip2. I can only assume it mentions cannot exec “lbzip2” due to using this as a dynamic library. If that isn’t the case, and if it is really wanting bzip2, then the “l” is corrupt and shouldn’t be there.

On my Fedora system there is a libbzip2 provided by Gnome. On an R28.2.1 Xavier there is no libbzip2 anywhere, but there is a libbz2, and it is in the default linker path.

As a test does the following list files without error (executed in same directory as “”):

bunzip2 < ./nv_tegra/nvidia_drivers.tbz2 | tar --list

The “” script is actually human readable, so it should be possible to narrow down what specific operation is causing this. Can I assume all of this was done from the “Linux_for_Tegra/” directory, and that both unpack of sample rootfs and run of “” were run with “sudo”? Do note that the sample rootfs must be unpacked prior to, so order of operation does matter in this case (the step depends on the directory structure in “rootfs/” created by the sample rootfs unpack, and much of this is owned by root).

In my ubuntu 16.4, there is only “bzip2” under “/bin”, then I create a link “lbzip2” linked to “bzip2”. Then the problem is solved.

I faced the same problem earlier, because lbzip2 library missing in your ubuntu system.

To solve it, just install lbzip2 as below.

sudo apt-get update
sudo apt-get install lbzip2

Hope it help!


Worked perfect — Fresh install of Ubuntu 18.04.5 LTS, nothing else. This error, and this solution. much appreciated.
