Bug#1135891: debmirror: User-Agent blocked by Ubuntu/Launchpad repositories

[Raphaël Halimi]

Package: debmirror
Version: 1:2.48
Severity: important
Tags: patch
Dear developers,

Since last week-end's DDOS attack, Canonical made some changes in their 
infrastructure and libwww-perl's default User-Agent string 
(libwww-perl/X.XX) is now blocked, making debmirror unable to mirror 
Ubuntu and Launchpad repositories.

This simple patch adds a User-Agent header specific to debmirror 
(debmirror/version), making it work again with those repositories.

Regards,
