Bug 1257335

Description of problem:
running from personal account:
opened gnome terminal...
% su
% passwd *******
% dnf update

Nothing happens for some time.  several minutes pass, no progress no output, nothing.

tried ctrl-C, no joy, dnf appears hung.

Killed the window by clicking on the X top right.

Window died, no apparent error message (notification did not appear at screen bottom).

Opened new terminal window...
% su
% passwd *******
%ps -ef | grep dnf shows the dnf command still running as process 4085, prior process 4058.
% kill 4085 
%ps -ef | grep 4058 shows the terminal process with no time.  and dnf process still hung.
% kill 4058
%ps -ef | grep 4058 shows the terminal process with no time.  and dnf process still hung.
%kill -9 4058
%ps -ef | grep 4058 shows both processes gone.  No notification at screen bottom on any commands.
Checked notifications.  Saw one for system.  sent this bug report.
