Package: exim4-config
Version: 4.84-2
Severity: important

Hi.

I ran into this problem when installing the roaming workstation profile
in Debian Edu Jessie.  I've seen in twice now, but it do not happen
every time.  The installation using debian installer fail because
exim4-config fail to install.  This is the syslog messages when this
happen:

Retrying still gave the same error.  Any idea what is wrong?  The
installation was running with dpkg, apt-get and tasksel diverted to run
using eatmydata to speed up the installation.  Is it somehow running out
of entropy?  What could be the cause, and why is it not happening every
time?
