Docker ROS dbus[xxx]: The last reference on a connection was dropped without closing the connection

问题描述：

最近在docker中安装ros后，启动rviz后，会出现如下报错

# rosrun rviz rviz
QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime-root'
[ INFO] [1614239106.900079430]: rviz version 1.13.15
[ INFO] [1614239106.900133052]: compiled against Qt version 5.9.5
[ INFO] [1614239106.900144142]: compiled against OGRE version 1.9.0 (Ghadamon)
[ INFO] [1614239106.911075450]: Forcing OpenGl version 0.
dbus[623]: The last reference on a connection was dropped without closing the connection. This is a bug in an application. See dbus_connection_unref() documentation for details.
Most likely, the application was supposed to call dbus_connection_close(), since this is a private connection.
  D-Bus not built with -rdynamic so unable to print a backtrace
Aborted (core dumped)

解决方法:

两种解决方法：

1.在docker run中添加--privileged参数

2.在docker run中去掉--network host参数
