@wbk Thanks for jumping in. So checking in the Host machine (admin@red.machine.yh) The user does exist both in the /home/ directory, and in the /etc/shadow `sudo su borg-user` (“queen” to follow the same example) does **not** prompt for a password and results in a CLI prompt like this (no prepending username@host): ```auto $ ``` The borg-user (aka ‘queen’) is not in visible in the admin panel of the Host machine. Also, before you posted your response, I noticed the Borg service on the Blue client machine failed. Checking the service logs I noticed the user was apparently “borg”, maybe because that was my initial username try the first time I attempted to install? So I uninstalled the Borg app on the Blue client machine, and installed it again. The same error remains on the borg service logs: > Could not start the service ‘borg’ > Recent service logs:-- Logs begin at Tue 2022-01-04 02:52:30 WET, end at Tue 2022-01-04 19:51:16 WET. – Jan 04 19:28:26 systemd[1]: Starting Run backup borg… Jan 04 19:28:26 sudo[10795]: borg : /etc/sudoers.d/borg is owned by uid 994, should be 0 ; TTY=unknown ; PWD=/ ; USER=root ; Jan 04 19:28:26 sudo[10795]: sudo: /etc/sudoers.d/borg is owned by uid 994, should be 0 Jan 04 19:28:26 sudo[10795]: We trust you have received the usual lecture from the local System Jan 04 19:28:26 sudo[10795]: Administrator.
