Public bug reported:

systemd name resolution is broken in professional setups.

https://askubuntu.com/a/974482 used to provide a solution, simply ignore
stub-resolution (which is broken) and fall back to the normal name
resolution as configured (e.g. through dhcp).

this solution does not seem to be available after upgrading to ubuntu
19.10 - there is no clean resolv.conf left.

please advise as to how systemd name resolution through its local
service can be disabled now (as it is broken).

Thanks

I expected my computer to resolve names (it used to do so after the
workaround for the systemd bug)

It does not resolve all names anymore (and the old workaround doesn't
work anymore).
