Hi Anthony!

Could you be so kind to tell me, can I use this template to install Ubuntu 22.04 by Foreman v 2.0 (install on CentOS 7), or it's very old version of Foreman and I must update Foreman before try this template?

this is specifically an iPXE template to trigger the autoinstall process for ubuntu 20.04 and later machines

this would be used if you use an iPXE based environment or more specifically if you use foreman_bootdisk with vmware compute resources

i would recommend upgrading to a much more current foreman release (current stable is 3.4.0) and there will be far less workarounds required to support ubuntu 22 installs and also refer to https://community.theforeman.org/t/autoinstalling-ubuntu-server-20-04-3-from-the-live-iso/27050/64?page=2 and https://docs.theforeman.org/nightly/Provisioning_Hosts/index-katello.html#Creating_an_Installation_Medium_for_Ubuntu_22_04_provisioning

Thank you @anthonysomerset
