Bug#202997: dpkg: Installing and disappearing a package in one go.

Package: dpkg
Version: 1.10.10
Severity: normal
Tags: patch


To rename a package with minimum impact on the user, I've created a
dummy package with the old name that pulls in the new package. The new
package replaces all files of the dummy package, which is then
disappeared. This doesn't work currently when both packages are updated
in one go because dpkg tries to configure the dummy package even though
it has already disappeared, eg.

 % dpkg -i dx-dev_4.3.0-1_i386.deb libdx4-dev_4.3.0-1_i386.deb

 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.

 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:                                     

The following patch (against dpkg 1.10.10) should fix this.
