Ethernet will not work on Ubuntu Server 20.04

in flag

I have a ASRock H570 Phantom Gaming 4 motherboard

I am unable to ping any other devices

  • When I ping duckduckgo.com I get "Temporary failure in name resolution"
  • When I ping 8.8.8.8 or another computer on the local network I get "Network is unreachable"
  • I tried to install net-tools and apache2 but they both gave the error "Temporary failure in name resolution"

I just installed my OS a few hours ago, everything is default and I have tested my Ethernet cable on other devices

ip a

Have you confirmed that the network device is recognized and active? What is the output of `ip a` and `sudo lshw -c network`?

It seems that I need drivers for my Ethernet. How do I install them without internet?

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.
