I have been also bitten by this with sympa-6.1.1~dfsg. I opted for "expert" (not using dbconfig) mode when installing sympa and the result was:
Installation script was saying that there is unknown database type (empty) as of course there was nothing configured in /etc/dbconfig-common/sympa.conf. I had to set database type there even if I don't want to use it. And rerun installation. Then it overwrote my database settings in sympa.conf (comment old out values and set empty/wrong values). And so it again failed installing it. I just could not make values stick. -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
