cloud-init timeout on boot

[violetevergarden]

  When use autoinstall to boot I get some error information like this:
  cloud-init failed to complete after 10 minutes of waiting.This suggests a bug……
  I'm not sure if it's due to the package version of cloud-init,because it works well when I not upgrade the iso file.The cloud-init package version before upgrade is 24.1.3-0Ubuntu3,then upgrade to 24.1.3-0Ubuntu3.3.
  Here is my user-data file:

Hi violetevergarden and thanks for the report,

Hmm I wonder if the following is relevant from the syslog:

Could you provide details on which ISO you're using? Also, could you describe your process for updating cloud-init a little more (how and why) please?

Thanks,
Chris

Thanks for your comment.The original ISO is ubuntu-24.04-live-server-amd64.iso,but I use Cubic to custom it.Here is the page of this software:
https://launchpad.net/cubic
There is a 'Terminal Page' on the cubic,it's a virtual environment where you can customize your Linux file system.So I run the command 'sudo apt update && sudo apt upgrade' to update the package and then run 'sudo apt install some-package-name' to custom package.At last,I modify the grub.cfg and loopback.cfg for autoinstall.
The content of grub.conf like this:
menuentry "Try or Install Ubuntu Server" {
        set gfxpayload=keep
        linux /casper/vmlinuz boot=casper autoinstall ds=nocloud\;s=/cdrom/preseed/ quiet splash ---
        initrd /casper/initrd.gz
}
In my test today, the cause of the problem seems to be the Firewalld package not the cloud-init.If I try to not to run 'apt install firewalld',then everything seems work well……If you need the iso file,I put a url on the attachment.That's a OneDrive url link and it's the iso file that I test today.
Thanks for your help again!

Ah yes I think updating cloud-init in the ISO like this might lead to some problems. As you found I think the best course here is to not update it when modifying the ISO.
