Cannot open settings

[Sergey Zolotarev]

GNOME settings don't open. When you attempt to open settings through the UI nothing happens.

Steps to reproduce

1. Click on the top right corner in GNOME shell
2. Click on the settings icon
3. Settings don't open

Expected result:

GNOME settings window opened.

When running gnome-control-center from the command line:

[_LOG_LEVEL_INFO 11:42:36.356039] Application.vala:155: System Settings version: 2.0
[_LOG_LEVEL_INFO 11:42:36.356111] Application.vala:157: Kernel version: 3.19.0-10-generic

Removing pantheon didn't help, now gnome-control-center executable seems to be missing, even though gnome-control-center package is installed. Settings still don't open.

Status changed to 'Confirmed' because the bug affects multiple users.

Thank you for reporting this bug to Ubuntu. Ubuntu 15.04 reached End of Life in 2016. See this document for currently supported Ubuntu releases: https://wiki.ubuntu.com/Releases

Please upgrade to Ubuntu 16.04 LTS and re-test. If the bug is still
reproducible, increase the verbosity of the steps to recreate it so we
can try again.

I apologize that we are not always to respond to bug reports promptly.
Do feel free to report any other bugs you may find.

I just installed pantheon and elementary from Ubuntu 16.04, then tried kde a while and now turn to gnome 3. (Everything because Canonical lets Unity die)
As I went these way I got that bug. Its the same. When I try to open gnome-control-center nothing happens. When I open from terminal it says:

gnome-control-center
[INFO 11:37:57.623375] Application.vala:153: Systemeinstellungen version: 2.0
[INFO 11:37:57.623413] Application.vala:155: Kernel version: 4.4.0-78-generic
[ERROR 11:37:57.696918] [GLib-GIO] Settings schema 'org.pantheon.dpms' is not installed
/usr/bin/gnome-control-center: Zeile 20: 28797 Trace/Breakpoint ausgelöst (Speicherabzug geschrieben) switchboard $switchboard_options $requested_plug

So I think that bug is still present.
