Thanks Charles for your reply. Your suggestion "apt purge unattended-upgrades" implies that my deletion/removal of the file 50unattended-upgrades is insufficient. Is that correct?
I shall feedback to you if your suggestion works. By the way, is there a method to suppression notification of new software and/or security updates? (I assume that if I can receive notifications of software/security updates, it means that my OS is communicating with Debian servers in the background, without my knowledge. I don't like that.)
