apt-get upgrade s'est mal passé

[Rakotomandimby Mihamina <mihamina@mail.rktmb.org>]

Bonjour,
J'ai un souci avec l'upgrade d'une sarge:

#apt-get upgrade
[...]
Usage: install-keymap [ keymap_file | NONE | KERNEL ]
dpkg: error processing console-data (--configure):
 subprocess post-installation script returned error exit status 1
dpkg: dependency problems prevent configuration of base-config:
 base-config depends on console-data (>= 2002.12.04dbs-16); however:
  Package console-data is not configured yet.
dpkg: error processing base-config (--configure):

dpkg: dependency problems prevent configuration of console-tools:
 console-tools depends on console-common; however:
  Package console-common is not configured yet.
dpkg: error processing console-tools (--configure):

Errors were encountered while processing:
 console-data
 base-config
 console-common
 console-tools
E: Sub-process /usr/bin/dpkg returned an error code (1)


Donc je supose que tout ne s'est pas bien deroulé ... est-ce grave ?
Comment remedier ?
De quels autres renseignement auriez-vous besoin pour m'aider un peu SVP ?

Merci d'avance.
