@uga you have a very old nvOC script version which does not support the upgrade command. Either you do it manually if you are confident in managing git trees or you can simply grab a newer nvOC helper script from github, replace the old one, and there will be the upgrade command also.

@Ventero the coin setup section looks fine, the miner specific options are usually fine with defaults so revert them back to defaults (you can always see defaults in the 1bash.template). Those settings defines how the params you put for eth or other coins are glued together and passed to the miner command line.

@parentibule have you intentionally enabled nvOC to run as a system service instead of as gnome profile launch script or you don't know what I'm talking about? In the first case, open an issue for that on github. In the second one, have you ever run the nvOC install-service command? You don't have to if you do not intend to switch to service mode, but if you have ever done this in the past, even accidentally,  then check PR note here #149

edit:@parentibule I think there is a bug somewhere, we ill discuss it in github. For anyone else having problems with nvOC as a service the above general guideline is valid.
