I need to replace a
package with a custom one, which gets its own name (foo-origpackage). To allow it to be used as drop-in replacement, I added the Provides: origpackage line to the control file. apt-cache show foo-origpackage lists the "Provides" entry just fine. However, when I want to install a file depending on origpackage, it fails ("
Package origpackage not installed").
Is there some distinction between "real" and virtual packages I'm missing?
EDIT:
To be precise, what I want to replace is xen-utils-common for Squeeze. My tao-xen-utils-common has the following control file:
