Binary package hint: apt-listchanges

package: apt-listchanges

architecture: amd64

detailed description:

When I try to install apt-listchanges on (k)ubuntu 10.10 it tries to install two mail-transfer-agents (exim4 and postfix):

<cut>
michel@zeil:~$ sudo aptitude install apt-listchanges
The following NEW packages will be installed:
  apt-listchanges bsd-mailx{a} exim4{a} exim4-base{a} exim4-config{ab} exim4-daemon-light{ab} postfix{ab}
0 packages upgraded, 7 newly installed, 0 to remove and 0 not upgraded.
Need to get 3482kB of archives. After unpacking 8475kB will be used.
The following packages have unmet dependencies:
  postfix: Conflicteert met: mail-transport-agent which is a virtual package.
  exim4-daemon-light: Conflicteert met: mail-transport-agent which is a virtual package.
  exim4-config: Conflicteert met: postfix but 2.7.1-1 is to be installed.
The following actions will resolve these dependencies:

     Keep the following packages at their current version:
1) exim4 [Not Installed]
2) exim4-base [Not Installed]
3) exim4-config [Not Installed]
4) exim4-daemon-light [Not Installed]

Accept this solution? [Y/n/q/?] q
Abandoning all efforts to resolve these dependencies.
Abort.
</cut>

It seems to me this has something to do with the following:

* apt-listchanges recommends "exim4" or "mail-transport-agent" (but neither "exim4-deamon-light" nor "exim4-daemon-heavy".
* mail-transport-agent is provided by "exim4-daemon-heavy", "exim4-daemon-light", "postfix" (amongst others) but not "exim4".

When I install a MTA (in my case "exim4-daemon-light") manually, the installation of apt-listchanges succeeds without any problem.

This was fixed in 2.85.10, in which version `Recommends: exim4' was changed to `Suggests: default-mta', see https://bugs.debian.org/599667
