I am using Ubuntu 18.04 and sqlite version 2.8.17 .When I run:
sqlite OSM-OpenCPN2-MediEast-20200115-2320.mbtiles
from terminal its give me this:
Unable to open database "OSM-OpenCPN2-MediEast-20200115-2320.mbtiles": file is encrypted or is not a database
I downloaded mbtiles from openseamap.
Update: I could opened the mbtiles as a sqlite database but I am confused how do attract them and make them real map.I am using Qt5/c++ for make an offline map.
