[R-sig-Debian] Conflict Between R and multimedia repositories

[Lorenzo Isella]

Dear All,
I have just installed a fresh Debian testing (squeeze) on my system
(amd64 architecture).
I am experiencing some really strange problems in updating my system
whenever I have both the R repository and the multimedia repository
available.
This is my source.list (when I disable the multimedia repository)

~$ cat /etc/apt/sources.list
deb http://ftp.ch.debian.org/debian/ testing main contrib non-free
deb-src http://ftp.ch.debian.org/debian/ testing main non-free contrib

deb http://security.debian.org/ testing/updates main contrib non-free
deb-src http://security.debian.org/ testing/updates main contrib non-free

#deb http://www.debian-multimedia.org testing main

#deb http://<favorite-cran-mirror>/bin/linux/debian lenny-cran/
#deb-src http://<favorite-cran-mirror>/bin/linux/debian lenny-cran/

# Add R-repository
deb http://cran.ch.r-project.org/bin/linux/debian lenny-cran/
deb-src http://cran.ch.r-project.org/debian/bin/linux/debian lenny-cran/

This way I have no trouble to update/upgrade my system (only, I do not
see the sources of the R packages, but this is really a minor issue
for now)

However (and this is really odd...) if I uncomment the multimedia
repository this is what happens

So, now nothing works...
If I uncomment the R cran repositories and leave the multimedia
repository, then everything works fine.
Bottom line: apt-get (on my system) does not like to have both the
multimedia and the R cran repositories available simultaneously, but I
cannot see why there should be any conflict. I am puzzled also because
I do not get any warnings e.g. about wrong signatures etc...
Any help is really appreciated.
