As title, the issue is “fixed” by adding [arch=amd64,i386] just after deb on every deb line in /etc/apt/source.list as suggested here. However, note that some deb lines may be included under the folder /etc/apt/source.list.d. So don’t forget adding [arch=amd64,i386] to them also.
Another fix mentioned here is to remove the arm64 architecture completely.
sudo dpkg --force-architecture --remove-architecture arm64
It did the trick for me since I am not using the computer as the host anymore. But I doubt this would work if one still wants to use the computer as a Jetson host.
