Package: postfix Version: 3.2.2-1 Severity: serious Reason: Upgrade fails for non-default database types
Dear Maintainer,
Looks like I got bitten by #847242 again when upgradating from 3.1.4-7
to 3.2.2-1. Here is my original report, with the `apt install postfix`
output updated.
--8<--------------------------------------------------------------->8--
My main.cf contains
alias_maps = lmdb:/etc/aliases
alias_database = lmdb:/etc/aliases
Upgrading postfix to 3.1.3-5 fails as follows:
~$ sudo apt install postfix
[…]
The following packages will be upgraded:
postfix (3.1.4-7 => 3.2.2-1)
postfix-lmdb (3.1.4-7 => 3.2.2-1)
2 upgraded, 0 newly installed, 0 to remove and 33 not upgraded.

Postfix (main.cf) configuration was not changed. If you need to make
changes,
edit /etc/postfix/main.cf (and others) as needed. To view Postfix
configuration values, see postconf(1).
After modifying main.cf, be sure to run 'service postfix reload'.
Running newaliases
postalias: fatal: unsupported dictionary type: lmdb. Is the postfix-lmdb
package installed?
dpkg: error processing package postfix (--configure):
subprocess installed post-installation script returned error exit status 1
dpkg: dependency problems prevent configuration of postfix-lmdb:
postfix-lmdb depends on postfix (= 3.2.2-1); however:
Package postfix is not configured yet.
dpkg: error processing package postfix-lmdb (--configure):

Errors were encountered while processing:
postfix
postfix-lmdb
I believe this is because postfix-lmdb.prerm removes the dynamic map during
unpacking, and doesn't re-add it before postfix.postinst calls `newaliases`.
I guess the map should only be removed upon removal (`prerm remove`), or
should be re-added by the preinst script instead.
Setting the severity to serious as this also applies to
alias_database=cdb:/etc/aliases, and I guess to all postfix-* packages
for which the prerm script removes the dynamic map during upgrade. FWIW
reinstalling (using `apt install --reinstall postfix postfix-cdb`) fails
as well.
Thanks for maintaining Postfix in Debian!
Cheers,
