i want a photo to tranform it like that

There is no image (or working link) in your post.

Also, Gimp 2.8 is totally obsolete by now (replaced over 5 years ago by 2.10) (and you aren't even at the last published version, 2.8.22).

I upload the photo?

Ok, so we have the photo, but what do you mean by "like that"? There is some grain/fuzziness but it cold be your camera or the print process.

The photo is like someone paint it

To me this carry bag looks like an attempt at photorealism. Why do you want to transform a photo of a carry bag?

I think it's the other way around because there is a satellite dish in the picture.

However it is a trend right now to repaint photos to make them look like old posters. I have such a poster where the architecture is distorted exactly as if the picture was taken with a wide angle lens pointing slightly up.

As a start, it is all-sorts I think a photo of a gift bag planted on a new background. Then a "artistic" rendered photo planted over that.

You could try the gimp_gmic_qt plugin http://www.gmic.eu It is available for linux.
Edit: ...or maybe.. If you are using a flatpak Gimp then get the dedicated gmic plugin via the flatpak install command. If it is an ubuntu snap Gimp then I think you are out-of-luck.

Then it is experiment to try and find a filter(s) you like. This collection (1) is original (2) Dreamy Watercolor (3) Graphic Novel (4) Two filters morphology + corvo painting. Each of those has many settings, it is try and see.



Into the background, fit to size and a layer mask to blend in. As you see you do need a really good initial choice of subject to match the background. Not so good here You will get there with lots of practice.
