I don't think this is the exim config at all, but rather postfix. Note that this doesn't change much; you'd want to preseed the MTA configuration in debian-cd in this file: data/xenial/preseed/ubuntu-server/ubuntu-server.seed
For postfix, this means setting postfix/main_mailer_type to the value you want for No configuration. In any case, this is not a debian-installer bug; and at most a bug in the seed or in debian-cd. Assigning to debian-cd for now. ** Package changed: debian-installer (Ubuntu) => debian-cd (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1549319 Title: server iso install prompts for exim config To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/debian-cd/+bug/1549319/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
