L4T 36.2 apply_binaries.sh error

[Jerry-W]

Hello everyone，
I’m excited to hear about the jetpack6 update and I want to try it out. But now I have a problem, When I do apply_binaries.sh on my X86 Ubuntu 18.04 host, it gets an error: “QEMU binary is not available, looking for QEMU from host system Found /usr/bin/qemu-aarch64-static”. I had been using this host to install Jetpack 5&4 and everything worked fine.

In fact I can find /usr/bin/qemu-aarch64-static on the system.

I also referred to the reply to the forum post: $ sudo apt-get install qemu-user-static
There is another reply under: $ sudo apt-get install qemu-user-static binfmt-support
$ sudo dpkg-reconfigure qemu-user-static

But this still doesn’t work, looking forward to anyone who can help me solve this problem, thanks！

I notice that the error is: /dev/random: File exists. So I try to delete this file as well as the urandom file, and then I do sudo ./apply_binaries.sh. Now he reports an error: qemu: Unsupported syscall: 293.

I recall that the release notes mentioned that this requires updating the qemu-user-static package. So I update it with sudo apt-get update & sudo apt-get install --only-upgrade qemu-user-static, but it doesn’t seem to update anything, sudo./apply_binaries.sh is still not working.

Hi,
Is the host in Ubuntu 18.04 or 20.04? And please check python 3 or 2 is used while running the script.

My host is Ubuntu 18.04. Given the ability to install Jetpack5, I think python 3 or 2 is used.

Hi Jerry-W,

This is known issue in release note.

Jetson_Linux_Release_Notes_r36.2.0.pdf

To work around the issue, update the qemu-user-static package on the Linux host that is used to install to the latest version.

$sudo apt-get purge qemu-user-static
$sudo apt-get install qemu
$sudo apt-get install qemu-user-static

Hi Carolyuu，
I noticed that the release note states that qemu needs to be updated. I did update. Maybe I failed to update before. But now that I’ve updated it with the three scripts you provided, it’s still reporting errors: qemu: Unsupported syscall: 293.

Hi,

It actually does not bring any issues. You can just ignore them.
The warning is still there because the latest version of QEMU you can install on Ubuntu 18.04 is not new enough.
If you really don’t want to see it again, please upgrade to Ubuntu 20.04+, or maybe manually download the .deb package from Focal or Jammy repositories:

Ubuntu – Details of package qemu-user-static in focal

(I’m not sure if this works or not; maybe it will fail to install because of package dependency issues.)
