HI,what is the meaning of CDN?

29

I am guessing: CDN.
(content delivery network)

linuxdev is correct - Content Delivery Network. The CDN mirros files/packages in servers located around the globe to provide better access across different regions (i.e. better download speeds).

I still get the following error:
E: Failed to fetch https://repo.download.nvidia.com/jetson/t210/dists/r32.4/main/binary-arm64/Packages.gz File has unexpected size (8479 != 8232). Mirror sync in progress? [IP: 92.123.212.152 443] .
Is there any solution to this problem?

I am facing the same problem in India. Did the fix of NTP as suggested in forum but no effect.

same here. I am waiting for @WayneWWW @linuxdev @carolyuu or someone to address the issue. Thanks for writing on the issue.

39

I don’t know if those repo sites are designed to work only with login or not. I did try to manually navigate to here in a browser:
https://repo.download.nvidia.com/jetson/t186/dists/r32.4/main/binary-arm64

which (at least without login) failed to show that the URL exists. I ended up trying one less part of the file path, e.g., https://repo.download.nvidia.com/jetson/t186/dists/r32.4/, until the only thing left was https://repo.download.nvidia.com/, and still did not find content, and so I am guessing one has to authenticate somehow prior to those downloads working.

If it turns out that authentication is not needed, then it looks like the server might be either misconfigured, or else have file browsing disabled (I was not navigating to a specific file, I was only navigating to a directory as a whole). So I have no way of looking closer, but can “sort of” confirm the issue.

@saikishor,

Have you tried to configure the NTP time?

41

We just clean up some cache on the CDN. Please try again and see if the issue is resolved or not.

42

Yes for the NTP issue, It seems when you cleaned up the cache on your CDN, it seems to resolve our issue.

Thanks a lot again @WayneWWW

NTP and cache cleaning doen not worked for me.
I did fresh installation after delating all the files in “sdkmdownloads” and it worked.
May be some old file in sdkmdownloads was causing the probelm.
Thanks

45

Atleast for me, it worked straight away!. Reinstalling earlier didn’t help at all

I had previous version of 4.2, 4.3 and 4.4DP and all files were in the same diectory.
Thus one or more older files was trouble maker.
Probably a fresh installation after removing nvsdkm has helped.
