I have run the other commands in the guide, this worked 2 days ago on the same hardware. I am not sure what I am missing. Any thoughts?
apt-get --yes --auto-remove --show-upgraded \
> .--allow-downgrades --allow-change-held-packages \
> .--no-install-recommends \
> .--option Dpkg::Options::="--force-confdef" \
> .--option DPkg::Options::="--force-confold" \
> .install postfix openmediavault
E: Sense auto is not understood, try true or false.
