Upgrading iceweasel (aka mozilla) on squeeze

[Rob Hurle]

Dear Maintainers,

  I seem to have a problem upgrading Iceweasel.  I'm running debian
squeeze, pretty much standard.  My /etc/apt/sources.list is:

--------------------------------
debianrob [21:50] /home/rob#cat /etc/apt/sources.list
#

#RJH
#deb http://www.debian-multimedia.org squeeze main non-free
deb http://www.deb-multimedia.org squeeze main non-free
deb http://ftp.debian.org/debian/ squeeze-updates main contrib non-free
deb http://ftp.debian.org/debian/ squeeze main non-free contrib
deb http://security.debian.org/ squeeze/updates main contrib non-free

# For Opera
deb http://deb.opera.com/opera squeeze non-free

#RJH - for Firefox
deb http://backports.debian.org/debian-backports squeeze-backports main
deb http://mozilla.debian.net/ squeeze-backports iceweasel-release
--------------------------------

The result from doing either an "upgrade" or a "dist-upgrade" is:

--------------------------------
debianrob [21:54] /home/rob#apt-get dist-upgrade
Reading package lists... Done
Building dependency tree
Reading state information... Done
Calculating upgrade... Done
The following packages have been kept back:
  iceweasel
0 upgraded, 0 newly installed, 0 to remove and 1 not upgraded.
--------------------------------

When I try to find out what is happening, I get:

--------------------------------
debianrob [21:56] /home/rob#apt-cache policy iceweasel
iceweasel:
  Installed: 12.0-7~bpo60+1
  Candidate: 13.0-1~bpo60+1

        500 http://ftp.debian.org/debian/ squeeze/main i386 Packages
--------------------------------

The same thing happened on the previous upgrade and the only solution
I could find was to remove iceweasel and then re-install it - nobody
on the debian-user list could see what the problem was.  Can you offer
any suggestions as to why it won't upgrade?  Thank you very much for
your help.

Cheers,
Rob Hurle
