Autoinstall breaks with official live server ubuntu download version 20.04.2

[Rupesh]

Autoinstall with the network as an interactive option does work with focal fossa live server ubuntu version (https://cdimage.ubuntu.com/ubuntu-server/focal/daily-live/current/focal-live-server-amd64.iso)

Autoinstall breaks with official live server ubuntu download version (https://releases.ubuntu.com/20.04.2/ubuntu-20.04.2-live-server-amd64.iso)

We are stuck at one point because of this, and we have a release planned in a week. Can you please tell us when the next iso release is planned with bug fixes? If it's not going to be sooner then do we need to use a year-old iso?

Also, What is the difference between two ubuntu flavors though both have the same LTS support and using the same kernel(5.4) versions? What is causing interactive mode to be failed in the official download version?
Below is my setup :

Both boot configuration files /boot/grub/grub.cfg & /boot/grub/loopback.cfg has bellow parameter
ds=nocloud\;s=/cdrom/nocloud/

Configuration file isolinux/txt.cfg has below parameter
ds=nocloud;s=/cdrom/nocloud/

Path /cdrom/nocloud/ has two seed files
/cdrom/nocloud/user-data
/cdrom/nocloud/meta-data

We have mentioned network as interactive, when we try to install ISO with this user data, it does not show the network screen, and the installation gets stuck after first screen(once we select the launguage)

Config Content :
cat > /cdrom/nocloud/user-data <<EOF
#cloud-config
autoinstall:
version: 1
interactive-sections:
- network
identity:
realname: Ubuntu
username: ubuntu
hostname: ubuntu-server

EOF
cat > /cdrom/nocloud/meta-data <<EOF
#empty
EOF

Your bug report does not contain any information explaining how it breaks for you.

We have provide the cloud init user data content in the description. And when we try to install ISO with this user data, we have mentioned network as interactive, but it does not show the network screen, and the installation gets stuck after first screen(once we select the launguage)

And It seems, I am not the only one who is facing this issue,

I've tried an autoinstall file like that and it worked for me. Please supply logs of your failed attempts if you want us to be able help.
