[R-sig-Debian] Some troubles with signatures and packages

[Lorenzo Isella]

Dear All,
I am running debian testing on a i386 machine. I added cran2deb for
testing by adding this line to my repository list

# CRAN
deb http://debian.cran.r-project.org/cran2deb/debian-i386/ testing/

However, I am experiencing a few problems. See for instance

 Size mismatch
E: Unable to fetch some archives, maybe run apt-get update or try with
--fix-missing?

So it looks like I did not import the right key (well, I actually had
a look at http://debian.cran.r-project.org/ but then realized that I
had imported the key for main; where is the one for testing?).
I then managed to install cran-bb using the --fix-missing suggestion,
but I have no clue at what is going on.
Any suggestion is appreciated.
Cheers
