Public bug reported: It looks like that the netboot image found in "/ubuntu/dists/bionic/main/installer-amd64/current/images/netboot/ubuntu-installer/amd64" upload date 2.2.2018 is broken for unattended install.
With a preseed file, which was working with 16.04, 17.10 and 18.04 at the beginning the installation stop after trying to get network-configuration via dhcp. It looks like only a dhcp request for ip6 is done. Further it looks like, if there is a problem with dns resolution, because after a manual network-configuration is done, the download of the preseed-file (url from kernel startparameter) fails, with error- message >>tftp01<< not found. url from kernel startparameter: kernel ubuntu-installer/18.04/amd64/linux append auto=true priority=critical url=tftp://tftp01/preseed/systemd/preseed_2P_1F_2F.cfg vga=788 initrd=ubuntu-installer/18.04/amd64/initrd.gz -- quiet ** Affects: ubuntu Importance: Undecided Status: New ** Tags: networking preseed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1748169 Title: netboot image for 18.04 broken with unattended install To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1748169/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
