At the end of the day, of course, it's the job of the
failing application to advise the user about possible
reasons for it failing along the lines of:

"The server you were trying to connect to does not respond.
 Please make sure there's a server running at the given
 address. If you want to run a local server you might need to
 install and configure the "your-app-server" package."

This can be much refined by an application taking care of
its users. It could differentiate between local/remote
servers. It could even check for the install status of a
local server package.

I don't think dbc should play fixup for user-unfriendly
apps. It should suggest reasonable strategies but needn't go
out of it's way.
