hello
just share my experience with Nzbget paquet and DSM 6 (synology):
- create an USER called : "nzbget"
- install the Nzbget paquet from synocommunity.com
- give folder permission : go to "panel control" - Group (user) - choose " sc-download" (or could be "sc-media") -> give permission to nzbget folder destination in reading/writing
it helps me to :
- launch the paquet (avoid "paquet stopped ..." message)
- avoid "permission authorization message such as "could not create ...."
enjoy
