This problem does not always occur but it does once in awhile. And after many times flashing Jetpack in the past, I faced this problem eventually after flashing Jetpack 4.1.1 on Jetson Xavier. Particularly, you run into these update error when you try to
sudo apt-get update
So the way to fix this is to require modification on the
/etc/apt/sources.list file. You need to add
[arch=amd64,i386] in every line starting with
deb in the file like this:
For Ubuntu beginner:
- How to edit this file, you need superuser privilege
sudo gedit /etc/apt/sources.list(I use gedit editor, but you can replace it with other editor of your choice such as nano, vim, etc…).
- After editing, save the file and then
sudo apt-get updateagain, the problem should go away.

This is useful when a foreign architecture has been added, causing “404 Not Found” errors to appear when the repository meta-data is updated.)
