[PyQt] How do I get a QScrollArea to scroll?

[LavaCreeperKing]

A lot of people seem to have this problem. How do I get a QScrollArea to scroll. I have this code below that creates widgets and places them in lines in a QScrollArea to display information. I need to set 4 widgest per line and space them out properly to display all the needed information. The problem in I cant get the ScrollArea to scroll.

(Using PyQt5)

self.pkg_display = QtWidgets.QScrollArea(self)
self.pkg_display.setGeometry(10, 40, 801, 401)
self.pkg_display.setStyleSheet("background-color: White")
self.pkg_display.setVerticalScrollBarPolicy(2)
self.pkg_display.setWidgetResizable(True)
self.scrollAreaWidgetContents = QtWidgets.QWidget()
self.scrollAreaWidgetContents.setGeometry(0, 0, 801, 800)
self.pkg_display.setWidget(self.scrollAreaWidgetContents)

def update_list():
    pos = 0
    x1 = 10
    y1 = 2
    x2 = 393
    y2 = 5
    x3 = 700
    x4 = 756
    for i in filtered_name:
        cb = QtWidgets.QCheckBox(ui.scrollAreaWidgetContents)
        cb.setGeometry(x1,y1,361,23)
        cb.setText(i)
        vtext = QtWidgets.QLabel(ui.scrollAreaWidgetContents)
        vtext.setGeometry(x2,y2,291,17)
        vtext.setText(filtered_version[pos])
        stext = QtWidgets.QLabel(ui.scrollAreaWidgetContents)
        stext.setGeometry(x3,y2,51,17)
        stext.setText(filtered_size[pos])
        ib = QtWidgets.QPushButton(ui.scrollAreaWidgetContents)
        ib.setGeometry(x4,y1,21,21)
        ib.setText("i")
        y1 += 23
        y2 += 23
        pos += 1
    ui.pkg_display.update()

The code creates the widjets and places them in the ScrollArea(pkg_dsiplay), but it will not scroll.
If anyone is wondering I am working on a tool to replace dnfdrogora(A Linux graphical package manager tool)
