Public bug reported:
Investigating an issue for CTDB (LP: #722201), after suggesting a fix on
ss syntax to CTDB upstream project, we discovered that "ss" seems to be
broken in Ubuntu since Ubuntu Cosmic:

I have generated a pkg using upstream iproute2 source code and it does
not suffer the issue. I have generated a package using Ubuntu cosmic
source package, without debian/patches/*, and verified the issue still
persists (not being introduced by any of our packages, and being present
if vanilla upstream version used in Cosmic).
