Are there plans for 18.04 on TX2?

Regards,
Chris

Hi Chris, support for 18.04 on TX2 is planned for a future release of JetPack.

4

My TX2 keeps popping up a message at boot to upgrade to 18.04. Is this viable or will it come with new jetpack?

5

Never use the Ubuntu mechanism for distribution upgrade. You’ll need to use JetPack or the driver package for any upgrade.

6

Hi there, do you know where can we get the release notes on TensorRT 5.0? I had submitted a bug report regarding the deconv layers on trt and was waiting on that one.

7

Cuda 10 is not installing on my Jetson Xavier via Jetpack LT4 4.0. Has anyone else experienced this issue? This is what the log says:

Configuration file '/etc/apt/sources.list.d/cuda-10-0-local-10.0.117.list', does not exist on system.
Installing new config file as you requested.
E: Could not get lock /var/lib/dpkg/lock - open (11: Resource temporarily unavailable)
E: Unable to lock the administration directory (/var/lib/dpkg/), is another process using it?
8

Nevermind. I re-flashed the jetson and everything works fine.

In my attempt to install the software before the module arrives,
I get this error. System information is below.

Installing OpenCV 3.3.1 failed.

Hi tomacorp, does running “sudo apt-get -f install” allow you to proceed? If you aren’t able to build OpenCV from source, you may want to post this in a separate topic for follow-up from the JetPack team. Thanks.

11

Yes, I am able to proceed after
sudo apt-get -f install

What fooled me was that when I ran the installer again to get the other packages, the installer uninstalled OpenCV and stopped, and I needed to
sudo apt-get -f install
again.

Next I set the installer OpenCV Package Action to ‘no action,’ and the installer was able to proceed.
If this is how it is supposed to work, it would be nice to have it in the release notes.

I will file this in https://developer.nvidia.com/content/jetpack-feedback
Oops, I got a 403 forbidden on the jetpack-feedback form (and lost my message!)
Where should I post a topic about the problem and the work-around?

Thanks,
Tom

You can post it here to the Jetson Xavier forum, which covers JetPack issues too. That condition shouldn’t be required for everyone, so your feedback is useful for others who may encounter it.

13

Reading the log file, this is the error:

libcvaux-dev:amd64

(This is for the host install, which isn’t strictly necessary.)

Apparently, you need to

apt remove libcvaux-dev

before you install the CV provided with jetpack.

thx!

Hi mdd7p9k3, we are currently experiencing an issue with the server and working to resolve it. Stay tuned.

16

We are getting the HTTP 404 Not found error here in US when trying to download it. Is there any alternative location it can be downloaded from?

17

It seems that the issue have’t been resolved so far.

18

I am not able to download Jetpack 4 as well. Seem like the site is down.

19

Yes, IT is still working to restore the server / CDN service, hopefully it will be back up later today. Sorry about that.

Hi guys, the JetPack server has been restored. We refreshed the CDN, so if you have problems downloading, please clear your browser cache or try incognito mode.
