I ran into the same problems, and as I had a modified exim4-conf I moved away /etc/exim4 and tried to reinstall exim4-conf to no avail:
Running update-exim4.conf with bash -x I saw the following: [...] + UPEX4C_internal_tmp=/tmp/ex4XdyiYF + trap 'rm -f /tmp/ex4XdyiYF' EXIT INT TERM + gentmpconf + rm -f /var/lib/exim4/config.autogenerated.tmp + touch /var/lib/exim4/config.autogenerated.tmp ++ id -u + '[' 0 = 0 ']' + chown root:Debian-exim /var/lib/exim4/config.autogenerated.tmp + '[' -e /var/lib/exim4/config.autogenerated ']' + chmod 640 /var/lib/exim4/config.autogenerated.tmp + '[' -e /var/lib/exim4/config.autogenerated ']' + rm -f /tmp/ex4XdyiYF So for me the fix was to insert a return 0 after line 227 in update-exim4.conf.
