ubuntu linux machine fails to connect to wired network but recognizes ethernet cable
Clash Royale CLAN TAG#URR8PPP

I got a new Ubuntu/Linux machine (Ubuntu 18.04.1 LTS) that I am trying to connect to the internet for the first time, wired via ethernet cable.
Under Settings >> Network >> Wired, there is an On/Off toggle switch. I switch it on, and it says:
Connecting - 1000 Mb/s
However, after about 30 seconds a window appears saying:
Connection failed - Activation of network connection failed.
I run the following in the terminal, here is the output:
user@natasha:~$ sudo lshw -c network -sanitize
