JetPack Installation : The manifest file is broken.

Hi,

When I launch the “JetPack-L4T-3.2-linux-x64_b196.run” script, I get an error window “The manifest file is broken.” And the components manager is empty.
I’m connected to the Internet through a proxy, which seems correctly configured. My browser works fine, I’m also able to use ‘wget’ on any file.
I already tried to remove all files, and re-download the script on nvidia.com, with no luck.

I did some digging and some tests. With wireshark, I was able to see that the “manifest.json” is correctly downloaded 3 times
And when looking at the final “manifest.json”, it seems to me that it begins three times and never ends, therefore the “broken” error. Here is the content of the file (look especially lines 24-25 and 47-48).

            }, 
            {

Any idea why the installer send three “GET http://developer.download.nvidia.com/devzone/devcenter/mobile/jetpack_l4t/json/linux-x64/manifest.json HTTP/1.1” ?

Hi victor.minard,

Could you re-download JetPack and try again?
Thanks!

Hi carolyuu,

Thanks for your reply. I already tried that multiple times (and I just did it again), and it didn’t change a thing…

Hi victor.minard,

If you still got the issue, please check your proxy or firewall setting.

Hi again,

I did check proxy and firewall settings (it is written in my first post). I also already read all similar topics on the forum, none offering a satisfying answer. For example, the topic you cited only solution is to use a home network, which I can’t do. There must be a way to make it work behind a corporate proxy.

As I said in my first post, sniffing the network with wireshark shows that the file is correctly downloaded 3 times (why 3, why not once ?), but somehow ends up corrupted…

Already tried. Not working.

Hi victor.minard,

Please add NV_DEVTOOLS_FORBID_MULTIPLE_DOWNLOAD_THREADS=1 environment variable when running JetPack.
For example:

NV_DEVTOOLS_FORBID_MULTIPLE_DOWNLOAD_THREADS=1 ./JetPack-L4T-3.2-linux-x64_b196.run
