I am trying to setup an unattended installation (building a VMWare template) with Packer and Ubuntu 20.04.6 live server, using an autoinstall user-data config file.  
The problem is that the Ubuntu installation prompt for confirmation, despite of my user-data file.

The message is:  
“Add autoinstall to your kernel command line to avoid this.  
Continue with autoinstall? (yes/no)”

Help please!

This indicates you need to add “autoinstall” to the _boot\_command_ of the source in your packer file.

I have the below configuration, but still failing.

“boot\_command”: [  
“”,  
“”,  
"/casper/vmlinuz ",  
"root=/dev/sr0 ",  
"initrd=/casper/initrd ",  
"autoinstall ",  
“ds=nocloud-net;”,  
“”
