Hi,
Look's like the layer manager in QGIS has got files names, layer names
and aliases all mixed up for rasters in gpkg. When renaming the raster
in the layer manager, one only changes the layer alias so the original
file name and layer name remain the unchanged, thus, you can't copy the
raster over itself as only file name and layer names are used. I guess
you can only delete the raster using the database tool as opening it in
the file browser will automatically lock the file for reading, which
makes sense.
This looks like a good bug report...

What happens to the raster name if you save 2 rasters in the
geopackage? This could be an issue with the naming conventions of
the layer manager instead of an issue with the file format…
When I look at the gpkg with DB Browser for SQLite, the table
associated with the raster layer has the correct name, but when I open
the gpkg in the Qgis browser, it has the same name as the gpkg.
What's odder is that I then added that raster to a different gpkg (one
that I created for the testing in the last email), and it keeps the
name, which is to say the name of the gpkg. I added that raster to a
blank map and renamed it. I then dragged it into the test gpkg, and
now it has the new name. So now I try to copy the renamed layer into
the original gpkg where is has the wrong name and get an error that I
can't copy the raster over itself (I used the original name). Even
with a different name I can't add it to the gpkg, as it appears to be
recognized as the original file. After backing up the gpkg, I thought
I'd delete the misnamed file and restore it from the project I added
it to. But you can't delete a raster from a gpkg if it's open in a
project. I'm baffled.
