Qt Install framework Icon creation in Linux does not work

[EndrII 0]

I Add into installer custom script to create icons, made in the example, after the launch writes that the command successfully but the desktop file is not created.

function Controller ()
{
    installer.uninstallationFinished.connect (this, Controller.prototype.uninstallationFinished);
    installer.installationFinished.connect (this, Controller.prototype.installationFinished);
}

Controller.prototype.installationFinished = function ()
{

    console.log ("start icons");
    if (systemInfo.kernelType === "winnt") {
        installer.performOperation ("CreateShortcut",
                               "@TargetDir @ / @ Name @ .exe",
                               "@DesktopDir @ / @ Name @ .lnk");
    }

    if (systemInfo.kernelType === "linux") {
    
        console.log ("start icons Linux");
    
        installer.performOperation ("CreateDesktopEntry",
                               "@HomeDir @ /. Local / share / applications / @ Name @ .desktop",
                               "Version = @ Version @ \ nType = Application \ nTerminal = false \ nExec = @ TargetDir @ / @ Name @ .sh \ nName = @ Name @ \ nIcon = @ TargetDir @ / icon.png \ nName [en_US] = YourApp_name" );

        installer.performOperation ("Copy",
                                       "@HomeDir @ /. Local / share / applications / @ Name @ .desktop",
                                       "@ HomeDir @ / Desktop / @ Name @ .desktop");
    }
}


Controller.prototype.uninstallationFinished = function ()
{

}
