My experience using the `/var/log/installer/autoinstall-user-data` file is that it will give errors. Each Ubuntu release contains a newer version of the installer, so the errors vary based on the release. I would use sample `user-data` files and merge in whatever sections you need customized. My stock `user-data` file is in this answer

The generated autoinstall-user-data had an extra level of 'kernel' in it. This has been resolved on the Subiquity main branch. For existing autoinstall files, if you have something like the following:

    package: linux-generic
