that is umbuntu. Didn't you say that keys.openpgp.org is the name that you can not resolve?
BTW - they look like they are having troubles and you've all but tested your network and your DNS and both are working, according to your results

You can try different DNS servers to see if this is a regional problem
dig +trace @1.1.1.1 keys.openpgp.org
THERE IS a current record that has not timed out from 1.1.1.1

That is a cached record and will not exist forever.
My guess is that there is nothing wrong with your set up, such as we can see, and we tried by examining all the moving parts, one by one.
It looks like it is out of your hands and openpgp.org is having troubles on an administrative level.
It is a twocows domain
