From my testing, Waydroid appears to be very buggy and not fully compatible with the default Kicksecure at the moment. For example:
Kicksecure uses xfce 4.18, which still doesn’t support Wayland by default.
Installing KDE, which supports Wayland, will cause the sdwdate-gui systray not to appear because it doesn’t support Wayland (there’s a ticket already open for this).
Waydroid has blocking issues when running on Debian, even if iptables is installed:
Installing waydroid inside kicksecure stopped here.
Reversing the ways:
Install Kicksecure inside Waydroid-Linux customized Debian version:
They say it’s based on Debian bookworm, which is stable, but actually, if you install the OS, the repos are sid, not bookworm. A ticket has been created:
Blocker: Kicksecure doesn’t support the unstable Debian version.
Installing Kicksecure inside waydroid stopped here.
