The solution to make the launcher trusted via command line is here but I don't know how to implement it for the LiveCD.

The solution is, aside from needing to be marked as an executable (chmod +x), that a metadata entry needs to be added via gio for xfce-exe-checksum with the checksum:

f=FILE; gio set -t string $f metadata::xfce-exe-checksum "$(sha256sum $f | awk '{print $1}')"

Which will result (running gio info FILE) with something like this:

metadata::xfce-exe-checksum: ab38b223e98fe8f2a28q2a11167d7c9c671096c4a7c5e495c9594f3ee75dfd93

Edit: Made an error here, will repost in a minute. Sorry!

Ok, this should set the desktop icon to trusted and avoid the error. It should also update the icon on both the desktop and Settings Manager to use the new ubiquity icon in the elementary-xfce-icon-theme. Hope I did it okay, feel free to change the in-file descriptions and formatting or whatever of course.

#!/bin/sh

# Use ubiquity icon for Desktop Launcher, set as trusted and mark as executable.

icon_name="ubiquity"
desktop_launcher="/home/xubuntu/Desktop/ubuntu-desktop-bootstrap_ubuntu-desktop-bootstrap.desktop"

desktop-file-edit --set-icon=$icon_name $desktop_launcher
gio set -t string $desktop_launcher metadata::xfce-exe-checksum "$(sha256sum $desktop_launcher | awk '{print $1}')"
chmod +x $desktop_launcher

# Settings Manager did not show changes when directly editing the snap launcher.
# So, copy the snap launcher to local apps, and update the icon on the local launcher.
# Settings Manager prefers the local .deskop file (if named the same), so this should replace the snap one.

snap_launcher="/var/lib/snapd/desktop/applications/ubuntu-desktop-bootstrap_ubuntu-desktop-bootstrap.desktop"
settings_launcher="/home/xubuntu/.local/share/applications/ubuntu-desktop-bootstrap_ubuntu-desktop-bootstrap.desktop"

mkdir "/home/xubuntu/.local/share/applications/"
cp $snap_launcher $settings_launcher
desktop-file-edit --set-icon=$icon_name $settings_launcher

Only issue with changing the icon is some themes might not provide it (Adwaita doesn't) so if a user tries out themes during the live trial and then goes back to install, the icon may be generic/missing. Maybe at some point the installer icon can be moved from elementary-xfce to the xubuntu-default-settings or wherever (and uniquely named) so that it always stays the same no matter which theme is chosen.

@bluesabre This issue (and the icon issue) were resolved, so I think this issue can be closed.

Launcher untrusted error fixed in casper: https://git.launchpad.net/ubuntu/+source/casper/commit/?id=e910c2777d9ecfa5d100111b3e5d2b0cd149b081

Icon reverted back to ubiquity name in Bootstrap installer launcher: https://github.com/canonical/ubuntu-desktop-provision/commit/15db38972b9d647000f3f50d169b2830c556b8b7

Good stuff. Closing out!
