However, this is the key missing bit. Yes, you need to pass this option when testing with d-i netboot images and then it will work. There is no way to automate this because the installer image does not know at any given point in time that it is a -proposed vs. an -updates image. So there is no further change to be made here in Ubuntu. ** Changed in: debian-installer (Ubuntu) Status: Triaged => Invalid ** Changed in: ubuntu-power-systems Status: New => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1702233 Title: Ubuntu16.04.3: Unable to install on Briggs system To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-power-systems/+bug/1702233/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
