Workaround was easy: in the live session the installer started for my convenience after the fault, I ran fdisk on each of the two disks to create a new gpt partition table, then reran the live installer. Worked great this time.
So: start terminal lsblk fdisk /dev/sda g w fdisk /dev/nvme0n1 g w run installer, choose erase disk and install ubuntu, select nvme... for bootloader destination reboot profit! -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1819057 Title: uefi install of ubuntu 16.04 crashed installer To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/1819057/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
