I set up a new machine today (one on which Lubuntu 20.10 installed successfully on AMD CPUs discussed in another thread). But I have a puzzling DNS issue:
Pinging another machine on the same network works only with a domain name (pinging this machine from the other machine works without the domain name). According to man resolved.conf, if I create a file under /etc/systemd/resolved.conf.d/ with a Domains = line that should work, but it does not (I have tried spaces around the = but that does not make a difference).
$ ping -c3 grunge
ping: grunge: System error
$ ping -c3 grunge.mybands.local

Suggestions welcome on where to look next. Thank you very much, in advance.
