Package: exim4-config
Version: 4.97-8
Severity: important

Dear Maintainer,

Im reporting a issue with installation of package exim4,specifically the exim4-config.
During the postintallation script the apt report that theres a error in
config file /var/lib/exim4/config.autogenerated.tmp on line 681. Next message
is that the "user mail was not found". Which result in exit status 1 of dpkg in config phase.
This leaves the exim4 in not fully installed state and prevent normal use of
apt afterwards.
To restore normal function of apt a had to force uninstall via dpkg -r with
force option.
I was using schroot with debian testing. This report is writen on system with debian stable.

Thank You
