Steps:
1) Create VM with serial port in ESXi

2) Customize ISO ubuntu-23.10-beta-desktop-amd64.iso to support autoinstall with attached file user-data.j2
   (Note: the variable {{ xxx }} will be replaced in file user-data.js before customize ISO)

3) Mount the customized ISO file

4) Poweron VM, it begins autoinstall

5) check output from serial output, find lots of error message

Expected:
For steps 5, won't hit lots of error "adlink /snap/subiquity/current: no such file or directory"
