Concave lens (diverging) produces an upright image that is virtual. Although to create a real upright image would require 2 convex (converging) lens with a distance of their respective focal lengths between them.
convex lens
Convex lens produces both real and virtual images. But concave lens produces only virtual images for real objects. If object is virtual then real image could be produced by a concave lens.
Because when you extend the light rays, they diverge and never meet. so you must always extend the light rays back behind the object, this will always result in the image being upright and erect. Meaning it will always be virtual, never real.
You are thinking of a lens. If it is to form an image you need a convex lens, also called a converging lens.
Light hitting the lens the eye is refracted. Imagine a bunch of drinking straws tied at the middle. If you fan out the top the bottom of the straws will fan in the opposite direction. So it is with the light through a lens. The angle of incidence bends all the light through the centre of the lens and out of the back of the lens. As light always travels in straight lines through a medium, that which was at the bottom on the way in is at the top on the way out and that which was on the left finishes up on the right. Therefore the image is upside down.
A converging lens produces a virtual image that is upright and enlarged, while a diverging lens produces a virtual image that is upright and reduced in size. Additionally, the converging lens forms the virtual image on the same side as the object, while the diverging lens forms it on the opposite side.
Image formed by a concave lens or a diverging lens is virtual,upright and smaller than the object.It is used by short sighted people.
No, a diverging lens cannot form a real image of a real object. Instead, it always produces a virtual image that is upright and located on the same side of the lens as the object. This occurs because the light rays diverge after passing through the lens, and they appear to originate from a point behind the lens.
The image formed by a concave lens is always virtual, upright, and located on the same side as the object. It is also diminished in size compared to the object.

A concave lens forms a virtual image of an object located at a distance greater than the focal length of the lens. The image is always upright and reduced in size compared to the object.
Convex lenses form real images and concave lenses form virtual images. But there is one case in which convex lens also forms virtual images. This is when object is placed between Principal Focus "F" and Optical Centre "O"
The image formed by a lens can be either upright or inverted, depending on the position of the object relative to the focal point of the lens. If the object is beyond the focal point, the image will be real, inverted, and reduced. If the object is within the focal point, the image will be virtual, upright, and magnified.
This image is always located in front of the lens.
Convex lenses can produce both inverted and upright images. Whether an image is inverted or upright depends on the position of the object relative to the focal point of the lens. If the object is placed beyond the focal point, the image will be inverted; if it is placed between the focal point and the lens, the image will be upright.
virtual, erect and diminished
In a concave lens the object always forms a virtual image. The convex lens also forms a virtual image.
