This is due to the fact that aptitude notices that the packages postfix-cdb and postfix-lmdb can be removed, so that they will not have been upgraded to their "transitional" versions, so that the old prerm script is run. This is the same kind of issue as https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1125017#10 I can reproduce the same issue with apt by doing what aptitude does: apt install postfix postfix-cdb- postfix-lmdb- I think that it is the postfix package that should entirely manage /etc/postfix/dynamicmaps.cf based on what is installed (which would have the advantage to rebuild it if for some reason this file gets lost or corrupt). If users are allowed to add their own maps, this could be done via a /etc/postfix/dynamicmaps.cf.local file, for instance. -- Vincent Lefèvre <[email protected]> - Web: <https://www.vinc17.net/> 100% accessible validated (X)HTML - Blog: <https://www.vinc17.net/blog/> Work: CR INRIA - computer arithmetic / Pascaline project (LIP, ENS-Lyon)
