thanks

Hi,

Here's a patch that fixes getaddrinfo() (derived from Aurélien's patch at
http://www.eglibc.org/archives/patches/msg00738.html).  Confirmed to work in
Ubuntu karmic, and uploaded in eglibc 2.10.1-0ubuntu6.

Cheers,

Bug#539950: when /etc/hosts doesn't exist, apt fails to resolve hostnames using libc6 2.10.1

2009-08-04 Thread Matthias Klose 

Package: libc6
Version: 2.10.1-0exp1
Severity: important

E.g. apt-get's call to getaddrinfo() returns with EAI_SYSTEM when /etc/hosts is 
missing and EAI_NONAME if /etc/hosts is empty. This is different from 2.9, where 
EAI_NONAME is returned in both cases, resulting in the regression in apt-get. 
`sudo whoami' prints an additional error message but works as expected otherwise.

This version does not even exists in Debian...
