Kace SDA - Ubuntu Installation Not Honoring Preseed Options and then Fails to Boot

I am following this guide and everything goes great up until I actually kick off a scripted installation of Ubuntu. The hardware is a 7th gen Lenovo Thinkpad X1 Carbon. I used the 64-bit PC (AMD64) server install image as suggested.

I've followed the steps in the blog post to the letter and I even copy and pasted the "Example Ubuntu GUI preseed file" word for word.

When I boot the laptop into the Ubuntu KBE the OS installation starts but I'm immediately presented with the first question "Choose a mirror of the Ubuntu archive". I'm then asked every other question by the installer after that point. It's almost like it is ignoring the preseed file entirely.

When I do allow the OS installer to complete by answering all the questions the computer reboots. I'm able to select "Ubuntu" from the Grub menu, but then after a bit of loading rather than booting to Gnome or giving me a terminal it says:

BusyBox v1.17.1 (Ubuntu 1:1.17.1-10ubuntu1) built-in shell (ash)
Enter 'help' for a list of built-in commands


Any idea of where I'm going wrong?

1-When was the last time your Metadata was updated?

Settings › Control Panel › General Settings

2- Are you on a Dark Network? (the device you are attempting to Image, has Internet access?).

3- If you go to your Source CD in Library > Source Media, Do you have any repositories there?

  • 1. The metadata was 4 hours old when I first checked. I updated it and tried another installation but got the same results.
    2. Not a dark network, it can get out to the internet no problem.
    3. Yes, I have the two listed in the blog post.

    One other thing that I'll add is that I messed around with the laptop settings. UEFI on, UEFI off. Secure boot on, secure boot off. Doesn't seem to make a difference. I also tried with a 6th gen Thinkpad X1 carbon instead of the 7th gen. It too gave the same results. - amo310 3 years ago

I am testing this again this morning. My metadata is updated as of 9-18. I am not sure this is metadata related. In my testing I am using a VM, it is in legacy(BIOS) mode, not UEFI and secure boot is off. My preseed file is running without any issues.

Couple of things that may be at work here. Your mirror locations are fine. So this leads me to believe that there is either a problem with the SDA getting out to the mirror, or there is some sort of hardware compatibility issue where the Boot environment cannot access the network or disk.

Usually when i saw that error message it was the preseed file with an issue, or the mirror could not be reached. But one way to eliminate part of this is to remove the mirrors and save the Source Media. Then try it again. This will force the system to JUST use the media on the SDA and not download the live patches.

Another question comes to mind here. Did you use the SERVER download of Ubuntu? You cannot use Ubuntu Desktop media, it has to be the server ISO. Also what version of Ubuntu are you using? I am using the current release 18.04.3. We will only support 18.04 and 16.04. Version 19 is not supported right now.

This is the media i am using currently:


Remember that you have to upload the full Ubuntu media, and not the network installer.

Once i finish this install i will test on UEFI mode in my VM and see if that causes any change.

  • Created new VM with UEFI mode. Exact same scripted installation is running without any issue.

    Here is the preseed file i am using, it installs the Ubuntu system with the default Ubuntu Desktop.

    - User created is called adminuser and the password is Admin123
    - Hostname is set to UbuntuImage
    - Forces use of SDA Cached Repository - but you can comment that out and add lines for the Ubuntu repo directly
