[PLUTO-help] Archvi Locali

[emc2]

Quando tento di installare il pacchetto mi da questo errore:


# apt-get install gnuchess
Reading Package Lists... Done
Building Dependency Tree... Done
The following NEW packages will be installed:
   gnuchess
0 packages upgraded, 1 newly installed, 0 to remove and 118  not upgraded.
Need to get 0B/88.6kB of archives. After unpacking 283kB will be used.
Err file: ./ gnuchess 5.07-1
   File not found
Err file: unstable/main gnuchess 5.07-1
   File not found
Failed to fetch file:/usr/local//usr/local/pool/gnuchess_5.07-1_i386.deb 
  File not found
E: Unable to fetch some archives, maybe run apt-get update or try with 
--fix-missing?

Come posso cercare di risolvere il problema? Credo dipenda da 
un'impostazione errata della directory contente i .deb ma non so dove 
andare a cercarla.

grazie
