Moi! The new version of the OpenDX toolkit now provides sane libraries, so I wanted to restructure the packages a bit. In particular, there is a new package libdx4, so I wanted to rename what used to be dx-dev package as libdx4-dev. This turned out to be harder than I thought.
The -dev package will usually be used for compiling local modules, so nothing within Debian depends on it. dx-dev's dependency on the main dx package is versioned with (= ${Source-Version}), so when trying to upgrade, apt wants to remove it without even considering to replace it with the new libdx4-dev (which conflicts, provides, and replaces dx-dev). So I created a dummy dx-dev package that simply depends on libdx4-dev. Works fine. But I also wanted to be nice to the user and automatically remove the dummy dx-dev once it's no longer needed. Therefore, libdx4-dev replaces anything in dx-dev, and dpkg removes the package. Works fine as well. Now the final problem is libdx4-dev and dx-dev are getting upgraded at the same time, and dpkg tries to setup dx-dev when it already has been removed: Preparing to replace dx-dev 1:4.2.0-8 (using dx-dev_4.3.0-1_all.deb) ... Unpacking replacement dx-dev ... Selecting previously deselected package libdx4-dev. Unpacking libdx4-dev (from libdx4-dev_4.3.0-1_i386.deb) ... Replacing files in old package dx-dev ... (Noting disappearance of dx-dev, which has been completely replaced.) dpkg: error processing dx-dev (--install): no package named `dx-dev' is installed, cannot configure Setting up libdx4-dev (4.3.0-1) ... Errors were encountered while processing: dx-dev The error can simply be ignored, but it's ugly, and I'd like to avoid it. So am I trying to do something stupid? Is there a better way to do it? Or should I simply go file a bug on dpkg? Any hints welcome, Daniel.
