Ubuntu20.04~ LTS pxe boot issue

PXE boot failing for Ubunto 20.04 LTS

Expected outcome:
VM should provision .

Foreman and Proxy versions:
Foreman and Proxy plugin versions:
foreman-tasks 6.0.0
foreman_remote_execution 7.1.1
katello 4.5.0
Distribution and version:
Foreman Server: Rocky 8.6

Client: Ubuntu 20.04 LTS
Other relevant data:

  • Download Unbunto 20.04 LTS ISO file and mounted and then copied contents into FTP location inside Foremand server.
  • during PXE boot seeing error “/init: line 49:can’t open /dev/sr0: No medium found”.
    after conituning this message for sometime the system is showing

“Unable to find a medium container a live file system”

And attempt interactive netboot from a url.

The system is looking for iso image…“https://releases.ubuntu.com/focal/ubuntu-20.04.5-live-server-amd64.iso

When tried with the above address it is saying bad address…

Anyway, looking to find a way to install from locally mounted ISO image.
