Subject: mdns-bridge: Unclean uninstallation blocks avahi execution; remediation via package re-installation fails due to PHP Fatal Error (Deadlock)

Description: Uninstalling the mdns-bridge package while the service is actively running (without prior manual deactivation) leaves the system in an inconsistent state that prevents the subsequent activation of the avahi daemon. This "phantom" active state persists across system reboots.

Critically, the standard administrative remediation workflow—reinstalling mdns-bridge to gracefully stop and disable the service—is obstructed by a separate issue. Upon re-installation, accessing the package configuration triggers a PHP Fatal Error (as detailed in a separate report), rendering the GUI inaccessible. This creates a deadlock scenario where the user cannot run avahi due to legacy conflicts, yet cannot access mdns-bridge to resolve those conflicts.

Steps to Reproduce:

Install the mdns-bridge package and enable the service (State: Running).

Uninstall the package via the Package Manager without manually stopping or disabling the service first.

Install the avahi package.

Attempt to enable/start the avahi service.

Result: The system reports a conflict, indicating mdns-bridge is still active/configured.

Attempted Remediation: Re-install mdns-bridge to regain control of the service state.

Navigate to Services > mdns-bridge to stop the daemon.

Observed Result:

Blocking State: The avahi service fails to start due to persistent configuration artifacts from the removed mdns-bridge package.

Remediation Failure: Upon re-installing mdns-bridge (Step 5/6), the system throws a PHP Fatal Error, crashing the interface. This prevents the administrator from stopping the service or clearing the configuration via the GUI.

His is ore was the Reason of the 1st Bug.

and i can Reproduce it i try it now 3 Times now i try deinstallin avahi 1st thene mDNS-bridge .
