Public bug reported:
In a fresh install of Ubuntu Server 20.04.1, netcat -vlp 8000 fails with
the following error message:
netcat: getnameinfo: Temporary failure in name resolution
Name resolution, both forwards and backwards, works as expected
elsewhere (e.g., ping or nslookup).
There's an upstream Debian patch that changes getnameinfo() errors into
warnings that should suffice. I'm not sure whether the underlying
getnameinfo() error is inherited as well, but neither Debian Buster or
Sid have such an error, nor does Ubuntu Server 18.04.5.
** Affects: netcat-openbsd (Ubuntu)
