I tested again, step (5) needs to be run in the /target, so here's an oneliner for both steps (4) and (5):
sudo sed 's/-signed"/"/' -i /usr/share/grub-installer/grub-installer; while [ ! -f /target/bin/efibootmgr ]; do sleep 1; done; sudo ln -sf true /target/bin/efibootmgr After entering that in a terminal, ubiquity can be started and it finishes successfully. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1648278 Title: Make Ubuntu 32-bit ISO image directly installable on UEFI machine To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2-signed/+bug/1648278/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
