[Koha] package install debian koha 17.11

Hy 2 all I wanted to test the "new" koha release by package install on debian jessie and stumbled on this: The following packages have unmet dependencies: koha-common : Depends: libplack-middleware-reverseproxy-perl but it is not going to be installed Depends: libtest-exception-perl but it is not going to be installed Depends: libtest-mockobject-perl but it is not going to be installed Depends: starman but it is not going to be installed any ideas ?
