cn flag

I recently upgraded my PC with new motherboard / memory and ryzen 7 Cpu , I have Ubuntu verison 18.04.6. I have a dual boot with Windows 10 ,after the upgrade the ubuntu side can't see the ethernet connection only the wireless connection. The Windows 10 is able to see and connect to ethernet without an issue.

ifconfig:

I've tried updating to solve this issue.

While the kernel can generally adapt to hardware changes, software and drivers configured for specific hardware usually do not adapt. Best practice is to reinstall the OS with a significant hardware change. Changing your motherboard is as significant as it gets. If I were you I would reinstall the OS

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.
