Bug#1138173: upgrade-reports: exim4-daemon-light installed unexpectedly

Package: upgrade-reports
Severity: normal
X-Debbugs-Cc: [email protected]

My previous release is: bullseye
I am upgrading to: trixie
Upgrade date: 2026-05-20
Method:

  1. Upgrade from bullseye to bookworm
    apt update
    apt upgrade --without-new-pkgs
    apt full-upgrade
  2. Upgrade from bookworm to trixie
    apt update
    apt upgrade --without-new-pkgs
    apt full-upgrade

- Were there any non-Debian packages installed before the upgrade?  If
  so, what were they?

  Yes. They are grafana, influxdb, and nginx. Probably unrelated.

- Was the system pre-update a 'pure' system only containing packages
  from the previous release? If not, which packages were not from that
  release?
  
  Probably unrelated.

- Did any packages fail to upgrade?

  No.

- Were there any problems with the system after upgrading?

  Yes.

  On bullseye/bookworm, gnupg Depends: gpg-wks-server.

  On trixie,
  1) gnupg Suggests: gpg-wks-server
  2) gpg-wks-server Depends: default-mta | mail-transport-agent.

  exim4-daemon-light got installed on trixie. It wasn't installed
  previously. And port 25/tcp is now listening. This is unexpected.

  Please consider note this unexpected behavior somewhere, probably
  release-notes?
