problem while installing debconf

[Baudin maxime <baudin@cnam.fr>]

for several versions now,
dpkg -i debconf returns an error message:

Unpacking replacement debconf ...
Setting up debconf (0.2.32) ...
dpkg: error processing debconf (--install):
 subprocess post-installation script returned error exit status 127
Errors were encountered while processing:
 debconf

where can I find more details about the problem,
I'd like to correct it.

sincerely,
max
