SDK Manager Can't Download / Corrupt .mtd file

Autonomous Machines Jetson & Embedded Systems Jetson AGX Xavier
1

When I try to run the download and installer in SDK Manager 1.4, I continually get the following errors for each package I am trying to download and install on my Jetson AGX:

ERROR: OpenCV on Target: The .mtd file is corrupt. Start a new download.

ERROR: OpenCV on Target: DevZone get download url failed: RequestError: self signed certificate in certificate chain.

I think it has to do with the SDK manager not being able to be passed the necessary certificate to access the web locations where these files are stored. Is it possible to manually download these files not through SDK manager and then do an offline install? Or does anyone know of a simpler fix.

Thanks!

Hi jimkel54,

Sorry for the late response, have you downloaded and ran the SDK manager to do the installation successfully?

Yes I downloaded and ran SDK manager for the install. I went through and manually downloaded all of the deb packages and that seemed to fix this issue however another issue arose.

I have successfully flashed the AGX with Jetson 4.5, however I cannot install any of the Jetson SDK components.

Some examples of error messages I am getting:

(This repeats for all packages)

Hi jimkel54 and kayccc,

I have exactly the same issue with downloading the SDK Components using SDK Manager. I have tried downloading them manually (wget) as got the following response:

$ wget https://developer.nvidia.com/assets/embedded/secure/tools/files/jetpack-sdks/jetpack-4.5/JETPACK_45_b129/OpenCV-4.1.1-2-gd5a58aa75-aarch64-licenses.deb

Any help appreciated.
Thanks

This is network issue. Can you please check your network environment and make sure the Jetson device can access internet, then retry?

Hello again,

I didnt hear anything back on my question, however I see there is a very different login process now for the SDK Manager - that required a login in parallel on a browser.

Now SDK Manager is happily downloading all the SDK components - so someone at NVIDIA has fixed this (thank you).

Over and out on this one.
Cheers
