This bug was fixed in the package netcat-openbsd - 1.190-2

---------------
netcat-openbsd (1.190-2) unstable; urgency=low

  * d/patches/misc-failures-and-features.patch: Refactor option/argument
    verification logic and re-enable usage of '-s' (local source address) and
    '-p' (local source port) in client mode (when '-l' is unset).  Regression
    introduced in version 1.187-1 of that file.  Closes: #897020, LP: #1767283.

Bug description:
  Hey,

  netcat shows a usage error if i try to use the "-s" option:

  Example in Bionic:

  $ netcat -s 127.0.0.1 127.0.0.1 22 < /dev/null
  usage: nc [-46CDdFhklNnrStUuvZz] [-I length] [-i interval] [-M ttl]
     [-m minttl] [-O length] [-P proxy_username] [-p source_port]
     [-q seconds] [-s source] [-T keyword] [-V rtable] [-W recvlimit] [-w timeout]
     [-X proxy_protocol] [-x proxy_address[:port]] 	  [destination] [port]

  Example in Xenial:

  netcat -s 127.0.0.1 127.0.0.1 22 < /dev/null
  SSH-2.0-OpenSSH_7.2p2 Ubuntu-4ubuntu2.4

  Manpage shows that the option is still availible and should work. Both
  systems use openbsd netcat.

  $ type netcat
  netcat is hashed (/bin/netcat)
  $ ls -lah /bin/netcat
  lrwxrwxrwx 1 root root 24 Apr 25 21:56 /bin/netcat -> /etc/alternatives/netcat
  $ ls -lah /etc/alternatives/netcat
  lrwxrwxrwx 1 root root 15 Apr 25 21:56 /etc/alternatives/netcat -> /bin/nc.openbsd
