Muon Update Manager launches, shows status, automatically begins a type of searching activity, and finally stops this odd "searching activity" (after about thirty seconds) to show the very same status a second time, then allowing the user to install the updates. However, sometimes the "searching activity" never stops, forcing the user to quit the program to try again. Usually, after one or two additional attempts, the "searching activity" successfully stops, allowing the user to install the updates. Today, even after six attempts, the odd "searching activity" never stopped. . . .

Reproducible: Sometimes

Steps to Reproduce:
1. Launch Muon Update Manager.
2. Observe its behavior.
3. Install updates if you can; otherwise, quit the program and keep relaunching it until the program finally allows the installation of updates.

Actual Results:  
Today (for the first time in about nine months), Muon Update Manager told me that the software is up-to-date (for about a second), but the odd searching activity that ensues never stopped to display the status permanently, a second time, as it has always done.

Expected Results:  
I expected the usual behavior, which is for the odd searching activity to stop to display the status permanently, a second time.

I don't mind odd behavior, as long as it is CONSISTENT behavior, so that I can execute my own behavioral procedures to accommodate the odd behavior and avoid problems; but, when behavior becomes unpredictable, I fear an eventual loss of control over the system. . . .
