Summary

When launching calamares installer in Solus-Xfce-Release-2025-11-29.iso live environment, following notification pops up:
Untrusted application launcher
The desktop file "calamares.desktop" is in an unsecure location and not marked as secure/executable. If you do not trust this program, click Cancel. Exec=/usr/bin/calamares-gui

This somehow gives a bad first impression for a new user who whishes to install Solus.

1. boot Solus-Xfce-Release-2025-11-29.iso live environment
2. double click on the Calamares desktop file on the desktop to launch calamares installer
3. user has to click on "Launch Anyway"

Expected result

Calamares should launch without error message. User should not need to click on "Launch Anyway"

Actual result

Error message appears. User has to click on "Launch Anyway" to launch calamares
