I am currently installing Ubuntu and I'm using the web-browser the Ubuntu installer has (luckily).

I am stuck with the error "ubuntu systemd-resolved[2309]: Server returned error XDOMAIN, mitigating potential DNS violation DVE-2018-0001, retrying transaction with reduced feature level UDP." Please help, I've been stuck here for I think about 2 hours. (I just got Ubuntu so I don't have any clue what to do...)

This is a previously discovered issue when using ubuntu with EDNS0 requests.. My understanding is that its no an error in ubuntu its a problem with the downstream server rejecting the valid request being sent to it.

The issue/reasons and answer is discussed in great detail here:-

Ubuntu 18.04 systemd-resolved error NXDOMAIN
