An Error has been detected when attempting to load Ubuntu 22.04.1

[Rudolf]

Hello whenever I attempt to deploy the image I get this error message. I am not sure how to proceed.

@Rudolf The output you have here shows the imgpath it’s looking for is /images/cinema/cinema.iso the deployed image should not be an ios, or is that just what you named your image?
Are you able to deploy other images?

[Rudolf]

@JJ-Fullmer
No I am not able to deploy other images, but I would imagine that’s because the other images are also ISO files. What should I be putting there instead? Sorry I am very new to this.

@JJ-Fullmer
For a full description of what we are trying to accomplish.

We have devices that run Ubuntu 22.04.1 with some custom software. We used to just copy 1 ssd to another, some issues came up with that process so we decided we should look into PXE. So essentially we want to have our devices be plugged in and they download an image and auto configure themselves without human intervention.

@Rudolf So Fog can do what you want there’s just a few steps you skipped.

Fog will essentially do the same idea of copying the SSD from one to another but in a more centralized manner with more customization capability.

Basically, you need to

• Install and configure the OS on a Virtual or Physical machine (virtual is easier to maintain if you already have a virtual infrastructure)
• Capture the image of that machine with fog
• Deploy the image to hosts

See https://docs.fogproject.org/en/latest/capture-an-image and https://docs.fogproject.org/en/latest/intro for some more info.

You can also expand further with customization of how you update your reference image, with windows there’s sysprep and other tools to help create a reference image, I’m sure linux has tools as well, I’m just not as well versed in them.

You can also edit the fog pxe menu to boot to an iso, I’m sure we have some examples in the forum for that.
There are also pre/post scripts so you can have a linux bash script that runs after an image is complete to do further customization of the image.

It sounds like Fog is the tool that will do what you’re trying to do, there’s just a bit more setup.
