I would like to make a Maemo 5 Hildon theme. I have taken beta theme (Digital Nature), renamed it to gamma (in index.theme), changed something with colors and want to turn it into deb (just to test what it looks like). I created folder structure: deb/usr/share/themes/gamma/index.theme, colors.config, backgrounds/, images/, others deb/DEBIAN/control and three other files I run in X Terminal dpkg-deb -b deb I get error tar: unknown option "--format=GNU" What should I do about it?
