Subject: 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.

The message tells about some problem in your system's locale support,
|
|
and you should investigate what the problem is.

|
|
+On Debian systems, if the DPKG_RUNNING_VERSION environment variable is
|
|
+set (to any value), the locale failure warnings will be suppressed just
|
|
+like with a zero PERL_BADLANG setting. This is done to avoid floods
|
