I am running ubuntu 22.04.1 very likely during the system update the nvidia driver got updated but after reboot they don't work anymore, no network card is detected through "ifconfig" command.

I believe other people had a similar issue in the past but I wasn't able to solve just by looking the two cases I found online.

here you can see that the only sort of network it detects is a connection to localhost. useless see picture 1

here it tells me the network cable is not connected while in reality it's connected see picture 2 thank you

I attach the output of journalctl with grep on network: click here to see it

I would also notice this when I look at the state of network dispatcher:

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
