I want to install and setup BackupPC on my ReadyNAS NV+ running RAIDiator 4.1.6 firmware. I installed the ToggleSSH, EnableRootSSH, and APT add-ons. When I ran apt-get install backuppc the installation seemed to go smoothly until the very end. I've posted the output here: http://pastebin.com/zkCJbjLN .
