problemi con apt

[Joif]

holà!
volevo bazzicare un po' sui repo di debian e dopo aver dato un sempice apt-get update mi ritrovo con questo bell'avviso:

Code:

W: GPG error: http://pkg-fso.alioth.debian.org unstable Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY E2B9DE6A8E7B323B

strano che manchi la chiave, così ho provato con un "apt-get install pkg-fso-keyring":

Code:

root@hackable1:~# apt-get install pkg-fso-keyring
Reading package lists... Done
Building dependency tree... Done
pkg-fso-keyring is already the newest version.
You might want to run `apt-get -f install' to correct these:
The following packages have unmet dependencies:
  aptitude: Depends: libapt-pkg-libc6.7-6-4.6
            Recommends: aptitude-doc-en but it is not going to be installed or
                        aptitude-doc
  libept0: Depends: libapt-pkg-libc6.7-6-4.6
  texlive-base: Depends: texlive-doc-base (>= 2007) but it is not going to be installed
                Recommends: dvipdfmx (>= 1:20050831-1) but it is not going to be installed
                Recommends: lmodern (>= 0.93.3-1) but it is not going to be installed
  texlive-base-bin: Depends: libkpathsea4 (>= 2007) but it is not going to be installed
                    Depends: libpoppler3 but it is not going to be installed
                    Recommends: texlive-base-bin-doc but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

e quindi ho seguito il consiglio ma, sorpresa, vuole rimuovermi qualcosa: aptitude, tasksel...

Code:

root@hackable1:~# apt-get -f install
Reading package lists... Done
Building dependency tree... Done
Correcting dependencies... Done
The following extra packages will be installed:
  libkpathsea4 libpoppler3 texlive-doc-base
The following packages will be REMOVED:
  aptitude libept0 tasksel tasksel-data
The following NEW packages will be installed:
  libkpathsea4 libpoppler3 texlive-doc-base

Do you want to continue [Y/n]?

da questo momento ogni apt-get che do mi riparte il solito avviso "E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution)".
il mio sources.list è quello di default della rev5:

Code:

deb http://download.hackable1.org/debian rev5 main
deb http://pkg-fso.alioth.debian.org/debian unstable main
deb http://security.debian.org/ lenny/updates main
deb http://ftp2.de.debian.org/debian lenny main

che si ha da fare? gli faccio eliminare quel paio di cose? grazie!

Cerca in mailing list: avevo risolto le stesse cose e scribacchiato come tempo fà.
