Geographic Information Systems Asked by MarkZ on October 3, 2021
Recently, I was looking for way to skeletonize buffer and besides solution with PostGIS and Postegre solutions there is algortihm v.voronoi.skeleton. I have tried to use it with different road/rail buffers as described in this tutorial (unfortunatelly in polish, though the best source I got).
Despite following instructions with different parametres and input layers I always get error with output and no layer is created.

I assume you are referring to the GRASS module v.voronoi, with the -s option to create a voronoi diagram around polygons. There is an open issue with this module.
I suggest that you first create centroids, and then try to run v.voronoi around those centroid points.
