Mike Hommey -- How to install Iceweasel 3.5 on Lenny

In my previous posts about the release of Iceweasel 3.5, some

people succeeded in installing Iceweasel on Lenny by rebuilding

xulrunner-1.9.1 (not without some trouble).

Actually, thanks to the improved dpkg-shlibdeps[1], it's almost

painless to install the packages from testing/experimental. The

old days where pulling a package from testing or unstable would

pull a new libc6 and a bunch of other packages are long gone

(though, as we will see, things could be even better).

So, if you are a Lenny user, are not afraid with a few packages

from testing on your system, and want to use Iceweasel 3.5, here

are the steps you can go through to install it:

- Add the testing and experimental sources to your apt sources:

$ echo deb http://ftp.fr.debian.org/debian testing main >

/etc/apt/sources.list.d/testing.list

$ echo deb http://ftp.fr.debian.org/debian experimental main >

/etc/apt/sources.list.d/experimental.list

- Set the default distribution to 'stable':

$ echo 'APT::Default-Release "stable";' >

/etc/apt/apt.conf.d/default

- apt-get update

- Install a few dependencies from 'testing':

$ apt-get install -t testing libstartup-notification0 libsqlite3-0

libnss3-1d libhunspell-1.2-0 libasound2

- Install iceweasel:

$ apt-get install iceweasel/experimental

The latter won't work until xulrunner-1.9.1 reaches experimental,

but the following alternative procedure will do in the meanwhile:

- Tentatively install xulrunner-1.9.1 (provided you downloaded it

following the previous instructions[2]):

$ dpkg -i xulrunner-1.9.1_1.9.1-1_*.deb libmozjs2d_1.9.1-1_*.deb

You will get dependency problems, ignore them.

- Fix the dependency problems:

$ apt-get -f install

This will install all the required packages from Lenny.

- Install iceweasel:

$ apt-get install iceweasel/experimental

Now, the sad thing about this, is that technically, you shouldn't

need to install libstartup-notification0 and libasound2 from

testing at all. The same might even apply for libhunspell-1.2-0.

The reason is that technically, xulrunner-1.9.1, which has a

versioned dependency on these libraries, doesn't actually require

the versions it demands, and earlier versions could work as well.

The ones from Lenny should be enough.

The reason why this happens is that these libraries don't provide

symbols files, which are the basis for the improved

dpkg-shlibdeps[3] to make better dependencies, ones that would

allow xulrunner-1.9.1 from experimental to work with Lenny's

libstartup-notification0, libasound2, and libhunspell-1.2-0.
