On a Kubuntu Neon desktop updated this morning, I go to System Settings > Regional Settings > Date and Time, enable "Set date and time automatically" then click apply. The GUI becomes unresponsive (can't close the window, can't activate anything, but the clock display continues to update). The machine is running standard ntpd configuration for Ubuntu, there's no need to enable the feature, but it shouldn't crash the application to attempt that enabling. Reproducible: Always Steps to Reproduce: 1. Enable "Set date and time automatically" 2. Click Apply Actual Results: GUI becomes unresponsive Expected Results: GUI should either request permissions to run ntpdate or report the failure to run it (note, ntpd is running on the machine, so ntpdate will likely fail even if permissions were set). Bonus points if the presence of a running ntpd were to make the settings module grey out or show the option as "checked", possibly with a note that this is not a KDE-managed process. Workaround: don't check the box on machines where it won't work, kill any hung systemsettings5 instances Here's the command line output from the hung process: $ /opt/project-neon5/bin/systemsettings5 "Theme tree: (Breeze)" Shortcut for action "options_configure" "Configure" set with QAction::setShortcut()! Use KActionCollection::setDefaultShortcut(s) instead. Shortcut for action "searchText" "" set with QAction::setShortcut()! Use KActionCollection::setDefaultShortcut(s) instead. Trying to open ksycoca from "/home/mcfletch/.project-neon5-kde//cache/ksycoca5" systemsettings: ntpUtility = "/usr/sbin/ntpdate" false QWidget::setWindowModified: The window title does not contain a '[*]' placeholder QWidget::setWindowModified: The window title does not contain a '[*]' placeholder systemsettings: Setting date from time server "Public Time Server (pool.ntp.org)"
Apparently the "hang" is actually an *extremely* long time out (long enough to fill out this whole bug report). The window eventually becomes responsive again, though when returning to the page the "Set date and time automatically" checkbox is again un-checked... some error and/or status warning would likely be appropriate.
I can confirm this, and it never does become responsive. I tested also my test laptop, which has Kubuntu 14.10 upgraded to Plasma 5, freshly updated and upgraded. On that one, there is no freeze; however, once I click Apply, it reports: You are not allowed to save the configuration. When I try to close the KCM, I get a popup: Apply Settings---System Settings The settings of the current module have changed. Do you want to apply the changes or discard them? and then Apply, Discard, Cancel buttons. Click apply: red X and Unable to authenticate/execute the action: 9, The backend does not specify how to authorize Definite bug.
Do you have polkit-kde-agent-1 installed and running?
You should see something like this: [ltinkl@goblin ~]$ ps aux | grep polkit ltinkl 8771 0.0 0.4 664928 34248 ? Sl 09:15 0:00 /usr/lib64/libexec/polkit-kde-authentication-agent-1

I do show a Polkit-kde, but it's a kde-4 version (this is on Kubuntu 14.04 with Neon 5 packages): mcfletch 25672 0.0 0.1 381644 16004 ? Sl Oct01 0:00 /usr/lib/kde4/libexec/polkit-kde-authentication-agent-1 potentially this might be down to having the wrong version running?
I am also getting this behaviour in a Kubuntu/KDE5 installation. I tried running sudo systemsettings5 and have the same result (are we sure this is an authentication problem)? Peter.
Git commit b6ae01ca8ea776c97cc57836401ca9696e2529e8 by David Edmundson. Committed on 14/02/2015 at 13:50. Pushed by davidedmundson into branch 'master'. Add systemd support into the clock KCM as an optional dependency The current time setting helper is incredibly broken. It manually tries to run a range of NTP utilities, all of which are deprecated. We can just call timedated directly and cut out the middleman as it has uses polkit anyway. This is currently an optional dependency, and the original helper still exists. It makes the code messy, but we have users to support for now.
