Remove Color Attribute Table - GDAL - geoTiff

Question

How can I remove the GDALRasterAttributeTable with GDAL? It interferes with styling in Geoserver.

GDALInfo output below:

Answer 1

My solution was to run a /usr/bin/gdal_calc.py -A input.tif --outfile=output.tif --calc="A*1" --NoDataValue=0 --co="compress=lzw"

Answer 2

From memory, the RAT/colour table for a tif is either stored in a .dbf or .aux.xml file. You could try deleting those if they exist.
