Package: exim4-config Version: 4.50-2 Severity: grave Justification: breaks debian installation
base-config runs a dpkg-reconfigure exim4-config as part of the Debian installation process so users get a chance to configure exim, which is initially installed noninteractively by debootstrap. With this new version now in unstable, I've noticed that my all my daily debian automatic installation tests of unstable installs have begin to fail, because the dpkg-reconfigure run hangs after the questions are asked. This is easy to reproduce: cow:/home/joey# dpkg-reconfigure exim4-config Restarting MTA: exim4. It will never return to the prompt. ps shows this: 4547 pts/1 S+ 0:01 | \_ /usr/bin/perl -w /usr/sbin/dp 4554 pts/1 Z+ 0:00 | \_ [exim4-config.] <defunct> Strace of the debconf process (4547) shows it blocked in read from fd 8: cow:/home/joey# strace -p 4547 Process 4547 attached - interrupt to quit read(8, I assume this is some sort of debconf/daemon interaction problem. The process tree also has an exim daemon running at this point. If I kill it, deconf stops blocking and returns. Presumably the code that runs this daemon no longer takes care to close file descriptors connected to debconf. FWIW, this system has debconf 1.4.46 installed. -- see shy jo
