Are you sure you want to continue connecting (yes/no/[fingerprint])?

At first open terminal and update the system using the following command:

Create ~/.Xsession with whatever you want to start. You might want to throw in a few lines to avoid screen blanking and screen savers:

sudo nano .Xsession

To solve this issue ,In visual Studio go to project menu and click on project properties under Platform target
and uncheck the Prefer-32-bit.

After that rebuild the project and run the application.

 public void CreateGraph(ZedGraphControl zg1, SQLiteConnection mbConnection)
        {
            zg1.GraphPane.CurveList.Clear();
            Console.WriteLine("Just Click on Humidity");
            GraphData sd = new GraphData();
            sd.getGraphData(mbConnection);

            //  List<Double> valueList = new List<Double>(sd.dateHumidity.Values);
            //  List<string> keyList = new List<string>(sd.dateHumidity.Keys);

            /* for (int i = 0; i < sd.x.Count; i++)
             {
                 pList.Add(sd.x[i], sd.y[i]);
