-s source iso sed can't read

I am trying to specify a source iso file and the process fails out.

bash ubuntu-autoinstall-generator.sh -a -u user-data -d /home/laughingman/ubuntu-autoinstall.iso -s /home/laughingman/ubuntu-autoinstall-generator/hirsute-live-server-amd64.iso -k

Any ideas?

On another note, thank you for this script. It saves a lot of time doing manual steps. Keep up the great work.

Hi, thank you for your report. I am able to replicate the issue and it turns out that the Ubuntu 21.04 (Hirsute Hippo) ISO does not follow the same structure as the 20.04 one does. This causes sed to fail because, as it prints out, the file does not exist. For now the only supported OS ISO is Ubuntu 20.04 server, however I have started working on adding support for 21.04 as well. I just need to figure out the right mkisofs command because the one currently in use doesn't work for the new ISO.

Separately, thank you for your feedback. It is much appreciated.

Do you already have a fix for this? I'd like to create an autoboot image for 21.10, which has the same issue.

I have the same issue with 22.04
