Hi,

suricata uses apt-cache in debian/control but apt is not essential nor a
biuld dependency so this does not work when apt is not installed, for
example on:

https://reproduce.debian.net/amd64/#suricata

Instead of apt-cache you can rather use dpkg-query like this:

-LIBHTP_PKG_VERSION=$(shell apt-cache policy libhtp2 | grep Installed | cut -f2- -d: | cut -c2-)
+LIBHTP_PKG_VERSION=$(shell dpkg-query -W -f '$${Version}' libhtp2)

This makes the package reproducible.

Cheers Jochen
