Hi,
giuseppe:~# dpkg -P backuppc (Reading database ... 87999 files and directories currently installed.) Removing backuppc ... Stopping backuppc: ok. Purging configuration files for backuppc ... and stop...
The postinst script seems to be stuck in db_purge, a line which was added automatically:
...
# Automatically added by dh_installdebconf
if [ "$1" = purge ] && [ -e /usr/share/debconf/confmodule ]; then
. /usr/share/debconf/confmodule
db_purge
fi
# End automatically added section
...
So it may be a bug in dpkg ?
Ludo.
