"The automatic download of the update is currently not available."

I've got LibreOffice 6.0.5.2 and an update to 6.0.7 is said to be
available when I check for updates in the help menu of LOWriter. I get
the notice in the subject line showing at the same time. I can and have
installed from a manual download and there's no burning issue to
upgrade now, just curious, is this going to change? Or can I do
something to make it available?

I'm using Linux Mint 18.3.
