I see. Some of the post/preinst scripts in Debian are not very robust
against minor important errors. For example, some servers with
startscripts in /etc/init.d will fail installation if their scripts
cannot be stopped or started, even if they are not supposed to be run
immediately. This is very seldom, but happens. Then, it also makes
installation inside a chroot environment a tricky task.
Your workaround of temporarily fixing the postinst or prerm scripts in
/var/dpkg/info is what I sometimes do in these cases, too. Easiest way
is putting an "exit 0" on top of the script in question, and removing
this line again after installation. But you have to make sure that
eventual configuration tasks, like creation of symlinks or changes in
configuration files triggered by the script, are nevertheless completed,
otherwise the packages config may be broken.
Of course, it is good style and recommended to report problems with the
installation scripts to the packages maintainer by "reportbug", so that
it may get fixed in future versions.
