postinst and debconf again

[pp <pp@infoglob.com>]

I posted my problem some time ago.


postinst script:

#! /bin/sh -ex

. /usr/share/debconf/confmodule
db_version 2.0
db_title "Midgard library package."

if  $mysqlcmd -D mysql -e 'use midgard;' >/dev/null 2>&1 ; then

        db_input "high" midgard/error
        db_go
        db_stop
else
db_input high midgard/do_setup || true
db_go



Output:

+ db_title 'Midgard library package.'
+ echo 'TITLE Midgard library package.'
+ local 'IFS=
'
+ local _LINE
+ read -r _LINE
+ RET=0
+ return 0
+ /usr/bin/mysql --user= mysql -e 'select * from user;'
+ mysqlcmd=mysql
+ mysqladmcmd=mysqladmin
+ mysql -D mysql -e 'use midgard;'
+ db_input high midgard/error
+ echo 'INPUT high' midgard/error
+ local 'IFS=
'
+ local _LINE
+ read -r _LINE
+ RET=question skipped
+ return 30
dpkg: error processing libmidgard (--install):
 subprocess post-installation script returned error exit status 30
Errors were encountered while processing:
 libmidgard


debconf -s postinst
runs without any problem 

Any hints??
