The correct fix for #601977 is for
cyrus-sasl2-mit-dbg and cyrus-sasl2-heimdal-dbg to Replaces: cyrus-sasl2-dbg.
Neither Pre-depends nor Conflicts, nor adding more Depends are going to fix it.

How do you know the user will get the right one ? If the user can get the wrong one,
then what is the point ?

It does not. Only Replaces can do that.

In that case cyrus-sasl2-dbg should have been called cyrus-sasl2-common-dbg and not depend
on anything.
