There are a few ways, it all depends on your image.
Built into Gimp is the clone tool - https://docs.gimp.org/en/gimp-tool-clone.html
Use a fuzzy brush, ctrl-click to select a source, carefully paint over the shadow.
Sorry, I had trouble finding a photo with lamppost / shadow but 30 second example

Another way is create a selection next to the shadow copy / paste and move the pasted area over the shadow.
Using 3rd party plugins.
The usual is a set of plugins resynthesize / heal selection. For linux you might not have python support needed for the heal selection plugin. - Tell us what Gimp / linux you use.
There is also the gimp_gmic_qt plugin which has inpaint filters. Paint a mask using the pencil tool and apply the filter. 30 second example this https://i.imgur.com/Wbimfmi.mp4
If you do a search, many tutorials using all methods.
