Support for 22.04 #30

Just tried it on 22.04 and it fails here: |

It's far from perfect but I was able to generate a 22.04 Server ISO with the following modifications: diff --git a/ubuntu-autoinstall-generator.sh b/ubuntu-autoinstall-generator.sh

I would also really like this for ubuntu 22.04, any help getting it up and working :-) |
|
Can confirm that the solution that @NetForces posted works. We use Idrac & NFS to mount iso's. Perhaps there are some flags you are missing when making your usb bootable @dcd-arnold. |

Hi @eddie4, I do nothing else than

@eddie4 try adding back the I may have time to try it myself today as having it working on a USB key is also my goal. |
|
Ok so far no luck in generating a working USB key... |
|
I've run into the same problem @dcd-arnold is facing — I can get a modified version of the script to run, but the resulting USB key (made using Etcher) won't boot a physical machine. It won't even try to boot. If I install the unmodified 22.04 ISO on a USB key it boots as expected. |
|
With the patch by @NetForces I can get a working USB stick. Just don't use Etcher, I've had bad experiences with that as well. Rufus (in Windows) does it flawlessly. Haven't tried dd yet. |
|
@Gertm are you booting to boot a BIOS (or UEFI with legacy support) or an UEFI machine? I try to boot UEFI. |
|
@dcd-arnold I'm booting a UEFI machine. I have the user-data file on a webserver so I can easily change it without having to remake the ISO all the time. |
|
@Gertm I copy it onto the iso with the command above. That seems to be the difference. |
|
@Gertm Your comment about Rufus vs Etcher is interesting. On my side, I have been using |
|
Ok I confirm that the same generated ISO works when using Rufus to copy it to a USB thumb drive and fails when using So Rufus is doing some kind of changes. I'll compare a USB key made with the 2 methods and see if I can find out what is done. |

So the contect of the Rufus generated USB thumb drive and the dd: Rufus: |

I gave it my best shot and greated the pull request #33 |

Isolinux got deprecated starting 20.10 but looks like a solution has been outlined here: https://askubuntu.com/questions/1289400/remaster-installation-image-for-ubuntu-20-10 I haven't had time to test though EDIT: |
I followed your updated version for 22.04, I booted the iso on a usb using rufus and tried to run the ubuntu but it just gets stuck and boot screen and doesn't go beyond. Did I miss something or is there something in addition to what I have to do? |
To be honest, I can't remember. I switched to using pxeless (see a few comments up) and have not maintained any interest in this project anymore. |
Thank you for your reply and mention of pxeless as this actually helped solve my issue and I was able to generate the iso. |
|
Hi @majidalikhan8baader, can you tell me how you solved it? Did you achieve it only with the pxeless project? |
@agusserraa98 Since I needed the ISO only, I shifted my concentration to the pxeless project and it was quite easier and properly documented. So, this helped and yes I was able to achieve it only using pxeless project. |
|
Great, use the Pexels project and it's really good, very well documented. Thank you |
|
I recommend PXEless as well instead of this project: https://github.com/cloudymax/pxeless/ |
Hi folks! I've been trying, unsucessfully, to modify this script to install beta versions of Jammy Jellyfish. The release candidate should be out today — any chance this will be updated for 22.04 support?
