Warning: The postinst maintainerscript of the package spark-store
Warning: seems to use apt-key (provided by apt) without depending on gnupg or gnupg2.

Note: Check first if apt-key functionality is needed at all - it probably isn't!
Warning: apt-key should not be used in scripts (called from postinst maintainerscript of the package spark-store)
