Yes I can reproduce. You should remove davmail before. > Please ensure that davmail-server has sufficient Breaks and Replaces > declarations. I'm not sure I should add anything, because the upgrade works well: (bullseye-amd64-sbuild)root@skade:~# apt install davmail [...] (bullseye-amd64-sbuild)root@skade:~# sed -i 's/bullseye/bookworm/' /etc/apt/sources.list.d/debian.sources (bullseye-amd64-sbuild)root@skade:~# cat /etc/apt/sources.list.d/debian.sources Types: deb URIs: http://deb.debian.org/debian Suites: bookworm Components: main contrib non-free (bullseye-amd64-sbuild)root@skade:~# apt update [...] (bullseye-amd64-sbuild)root@skade:~# apt update && apt install davmail [...] Setting up davmail (6.0.1.3390-6) ... Removing obsolete conffile /etc/init.d/davmail ... [...] and all is well. Maybe this requires apt. Or do you suggest this manual install should be supported? Thanks, Alex
