[SOLVED] Problem with Ubuntu 24.04 installation

Good morning,
At the end of July, I was on WAPT Server version 2.6.0.17293 and I was able to deploy Ubuntu 24.04 without any particular problems.
I updated WAPT Server to version 2.6.0.17392 and I just noticed that the Ubuntu deployment was failing at the beginning of the installation.
The error is 'Unable to find a live system on the network'.

To be sure, I just recreated a blank deployment configuration:
- by loading a config from the config_ubuntu_desktop.conf file on which I remove everything from the late-commands line.
- by loading the IPXE script from the ubuntu.ipxe file
But the problem is still there.
I was wondering if there was a modification to the ubuntu.ipxe file in the latest updates.
Sincerely

Hello
, quick question: how much RAM is available on the machine? (

Good morning,
This machine has 32GB of RAM.
Would it be possible for you to test an Ubuntu installation on your end, perhaps?
[edit] After looking on various forums, it seems to be a matter of the kernel, initrd, and iso versions not being identical. The 'ignore_uuid' option added to the kernel line seems to solve my problem. I don't know why this Ubuntu-related error is occurring now. [/edit]

Hello,
good catch! I just realized why Ubuntu 24.04.3 was just released, and the URL specified in the IPXE script is 24.04.2.
Ubuntu updated the initrd to the corresponding link, so it's a mismatch. I'll check if that's the issue. (I'll try tomorrow)

Good morning,
Yes, you're right, that was it
I corrected the path to the ISO this morning in the IPXE configuration and everything is working correctly again
Code: Select all
kernel http://releases.ubuntu.com/noble/netboot/amd64/linux initrd=initrd root=/dev/ram0 ip=dhcp cloud-config-url={{server_url}}api/v3/get_wads_config?mac_address=${net0/mac}&conf_only=true&ip_address=${net0/ip}&uuid=${uuid} url=https://releases.ubuntu.com/24.04.3/ubuntu-24.04.3-live-server-amd64.iso autoinstall
initrd http://releases.ubuntu.com/noble/netboot/amd64/initrd
boot

Thanks for the feedback.
We need to find a latest URL for Ubuntu, but unfortunately, it doesn't seem to exist:
https://releases.ubuntu.com/24.04.3/ubu ... -amd64.iso
