I'm trying to understand that line

Broken mod-host:amd64 Depends on libreadline7:amd64 < 0~7.0-3 @ii mK > (>= 6.0)

Is that to say that libreadline7 must be below 7.0-3 specifically? So because I have 7.0-3 installed I can't use it?

Yeah. I need to build libreadline statically in order to drop this dependency.
