From 60779b8cb6df0eb694dab0c8991d7014a4a3140b Mon Sep 17 00:00:00 2001 From: Niko Tyni Date: Sun, 3 Oct 2010 21:36:17 +0300 Subject: [PATCH] Squelch locale warnings in Debian package maintainer scripts Bug-Debian: http://bugs.debian.org/508764 The system locales are rather frequently out of sync with the C library during package upgrades, causing a huge amount of useless Perl locale warnings. Squelch them when running package maintainer scripts, detected by the DPKG_RUNNING_VERSION environment variable. Any real locale problem will show up after the system upgrade too, and the warning will be triggered normally again at that point.
