Package: monodevelop Version: 5.10.0.871-2 The package control file include this:
Suggests: ..., monodevelop-debugger-gdb, ... Breaks: monodevelop-debugger-gdb Notice how it is conflicting with its own suggested package. I guess either the suggest or the breaks should go? The problem is not present in Jessie (version 4.0.12+dfsg-6). -- Happy hacking Petter Reinholdtsen
