I'm currently doing PXE automation installation Ubuntu 20.04 desktop. I'm following this guide https://www.laroberto.com/ubuntu-pxe-boot-with-autoinstall. but the guide is for Ubuntu live server image. I've successfully installed it, but when I tried to do it with Ubuntu 20.04 desktop this error occurred.

error

Here my configs.

  • Ubuntu Server 20.04 is compatible with cloud-init. Ubuntu Desktop 20.04 is not. The two are dissimilar due to a multi-year migration to a new installer. Server uses the new installer. Desktop uses the older (preseed-compatible) installer. – user535733 Aug 04 '22 at 04:11
  • thank you for your reply, in my configuration. i need to configure the preseed file instead of user-data cloud-init is it? – nabil_spect Aug 04 '22 at 04:16
  • Seems pretty clear that the instructions you followed are for installing a Desktop system from a PXE-boot using a Server image. You can do it that way -- the base Ubuntu system underlying both Desktop and Server is identical, different packages are on top of that base. You merely downloaded the wrong .iso – user535733 Aug 04 '22 at 04:23
  • for the ubuntu live server is successfully installed. but I need to install the ubuntu-desktop image. but cannot find the right configuration for automation installation. – nabil_spect Aug 04 '22 at 04:29
  • If you want to do it that way, see https://wiki.debian.org/DebianInstaller/Preseed . That's the format compatible with Ubuntu Desktop 20.04/ – user535733 Aug 04 '22 at 04:50
