Hi Nathaniel, yeah -a lso maybe the username is a red herring and the configfile is the actual issue.
You can follow [1] a bit. And also consider the env vars of dpkd-maintscript-helper and dpkg. So in your case likely something like: DPKG_DEBUG=1 DPKG_MAINTSCRIPT_DEBUG=1 dpkg -i /var/cache/apt/archives/exim4-config_4.87-3ubuntu1.deb If that is not enough DPKG_DEBUG=1 DPKG_MAINTSCRIPT_DEBUG=1 dpkg --debug=3773 -i /var/cache/apt/archives/exim4-config_4.87-3ubuntu1.deb Also what is the cotent (if still around) of /var/lib/exim4/config.autogenerated.tmp (and /var/lib/exim4/config.autogenerated)?
