A solution may be to specify the projection with a proj-string instead of an epsg code. https://epsg.io/25832 -> "+proj=utm +zone=32 +ellps=GRS80 +towgs84=0,0,0,0,0,0,0 +units=m +no_defs"
*Important: the proj strings you can find often include "+type=crs" but this is currently not supported by netconvert. It should work if you remove this component.* See https://github.com/eclipse/sumo/issues/12288 For the windows error message, please check whether the proj db is present in %SUMO_HOME%/share/proj (also see https://github.com/eclipse/sumo/issues/8497) For the linux error message, a possible cause may be a mismatch in proj version and found database version ( https://pyproj4.github.io/pyproj/stable/gotchas.html#internal-proj-error-sqlite-error-on-select ) regards, Jakob Am Di., 13.
