Hi,

automatic installation tests of packages that share a file and at the
same time do not conflict by their package dependency relationships has

This is a serious bug as it makes installation fail, and violate
section 7.6.1 of the policy. Possible solutions are to have the two
packages conflict, to rename the common file in one of the two
packages, or to remove the file from one package and have this package
depend on the other package. File diversions or a Replace relation are
another possibility.

Here is a list of files that are known to be shared by both packages
(according to the Contents file for sid/amd64, which may be
slightly out of sync):


  etc/default/sslh
  etc/init.d/sslh
  

This bug is assigned to both packages. If you, the maintainers of
the two packages in question, have agreed on which of the packages will
resolve the problem please reassign the bug to that package.

-Ralf.
