 If multiple packages obsolete an installed package, the solver checks the provides of every such package and ignores all packages that do not provide the installed package name\&. Thus, you can have an official update candidate that provides the old name, and other packages that also obsolete the package but are not considered for updating\&. If you cannot use this feature, you can turn it off by setting this flag\&.
