Is this from the host PC? These are all desktop PC architecture. If the Jetson itself is seeing this, then an incorrect modification of repositories was made (it should only look for “noarch”, “arm64”, or “aarch64”).

Also, there is a difference between failure to look up an address versus not reaching the address versus the server not finding something once that address is reached. The dotted-decimal address above belongs to Canonical, the Ubuntu people. Does this work?
host 185.125.190.36

If it works, then you have working DNS. If not, then do you get a response from:
ping 185.125.190.36

If that works, then you have a network route even if DNS fails. If DNS and ping works, then do you get a server page when you put 185.125.190.36 into the address of a common web browser? If this works, then you have access not only to the network, but also to the specific server on port 80. Errors after this would be related to not finding packages (versus not finding the server or network).
