>From f44b769bdf6da275a09ae3abe0decc835ba65875 Mon Sep 17 00:00:00 2001 From: Akira Yokosawa <akiyks@xxxxxxxxx> Date: Mon, 24 Sep 2018 11:26:02 +0900 Subject: [PATCH] Require updating a2ping to 2.83p on older distos Recent security fixes to Ghostscript [1] on Ubuntu Trusty and Xenial broke a2ping 2.77p. This change removes conditional of "Ghostscript 9.22 and later" in checking a2ping's version, and report error if 2.77p is found. Also update FAQ-BUILD.txt to provide nicer instructions to update.
