With Ubuntu Server 20.04 a new installer (called "subiquity") was introduced. And subiquity is a bit different compared to d-i.
For the transition phase we still have one (last) 20.04 GA image with d-i, available here (but already marked as legacy): http://cdimage.ubuntu.com/ubuntu-legacy-server/releases/20.04/release/ Since d-i is legacy, I of course recommended to use (and to become familiar) with subiquity. And subiquity is available here: http://cdimage.ubuntu.com/releases/20.04/release/ It operates a bit differently and requires (aot) some data that needs to be handed over via the parmfile. Please have a look here for some more details: https://ubuntu-on-big-iron.blogspot.com/2020/03/glimpse-at-subiquity.html On top one may of course also try the 'ready to use' cloud images (for KVM) or container images (LXD) - for their specific use cases. ** Package changed: linux (Ubuntu) => subiquity (Ubuntu) ** Also affects: ubuntu-z-systems Importance: Undecided Status: New ** Changed in: ubuntu-z-systems Assignee: (unassigned) => Skipper Bug Screeners (skipper-screen-team) -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1878596 Title: [Ubuntu 20.04] - Install - problem Status in Ubuntu on IBM z Systems: New Status in subiquity package in Ubuntu: New Bug description: Hello, I finally started installing Ubuntu 20.04 and running into a problem. I looked at the available documentation which seem to be similar to previous Ubuntu install on IBM Z. I punch the parmfile, initrd, and kernel into the z/VM rdr and IPL 00C using the exec supplied as I did before but it stop in the middle and went to a "emergency mode" instead of asking me for the network information as in Ubuntu 18.04. Here is the output of both during the installation. Any idea what I'm missing?
