JetPack4.4 or sudo apt-get update failure

I am trying flashing JetPack4.4 with SDK Manager on Nvidia Xavier AG, I am getting All package (opencv,cuda,cudnn,tensorrt) install failure after flash image success. I tried JetPack4.4.1 also with the same failures. I see below failure in SDK Manager

Error:
File has unexpected size (16348 != 20547). Mirror sync in progress? [IP: 23.194.190.169 443]
Hashes of expected file:

So, I tried Sudo apt-get update on flashed image and it gives me same “file has unexpected size” error. i checked date time sync on my xavier as other solutions and i find date time correct on the xavier. tried multiple times flashing Jetpack4.4 without any success. I am trying since a week multiple times a day.

Still getting the same issue on update File has unexpected size (16348 != 20547). Mirror sync in progress? @WayneWWW

This seems to be a temporary issue when mirror sync is in progress. Could you please retry later?
