In GIMP, I use the following sequence:


select a layer with an image
make a selection and copy it with Ctrl+C
create a new layer with transparency fill type
paste selection with Ctrl+V


Problem:
The content of copied selection is not pasted.

If I paste it on a layer with a white background, it is visible, but I want a transaparent background.

In the Channels tab, the Alpha Channel must activated.

Activated channels appear highlighted generally in blue in the Channels dialog (sometimes in grey). Inactive channels appear in white. If you click on a channel in the list, you toggle activation of the corresponding channel. Disabling the alpa channel has severe consequences. If you disable the alpha channels, all pixels from now on added to the image will not have alpha component, and so a pasted pixel will have the transparency of the layer on which it is pasted.

If the layer on which it is pasted is transparent, the pasted pixel will be transparent.
If the layer on which it is pasted is white, the pasted pixel will be visible.

This explains the behaviour you observed.

See docs.gimp.org/2.8/en/gimp-channel-dialog.html

Make sure that the transparent layer you added is the layer which is marked active in the Layers list when you paste. Otherwise you will be pasting to the same layer you copied from, with no visible results.

Don't forget to Anchor (Ctrl-H) if the paste looks OK.

Make sure the new layer you are pasting on has the blend mode set to normal.

After pasting using CTRL+V, hit the Anchor button in the layers palette to anchor the floating selection to the new layer you made.

Alternatively instead of hitting Paste (CTRL+V), use Edit > Paste As > New Layer - then you can skip the create new layer and anchor steps altogether.
