This is not how the preseeds work with d-i on Debian/Ubuntu. Specifying s390-zfcp/zfcp like that preseeds the answers for that question, however the question may still be shown. The questions shown depend on the priority of the installer (default is high) and thus this question will still be asked.
If you are trying to achieve fully automated installation, you would need to raise the priority of the installer to critical only; but also preseed answers for many other questions too. If you can still reproduce the problem, please extract and attach installer logs /var/log/syslog from the running / crashed installer. ** Changed in: ubuntu Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1638597 Title: installer session broken and cannot limit the luns display To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-z-systems/+bug/1638597/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
