my power went out recently and when it came back on, I'm not longer able to connect to the internet from my ubuntu server. I can still ssh into the server remotely from my laptop while I'm on my home network, but I can't ping anything from my ubuntu server once I've ssh in. I've run the commands below, and I also have their output. And just to make things interesting, sudo has also stopped working for me. I've tried powering off and rebooting the server, powering my router on and off, changing the ports the ethernet is plugged into. No luck connecting to the internet. Does anyone have a suggestion what the issue might be, and how to fix it?
