Error while trying to install Iceweasel 4.

[Imagus]

Can anyone please tell me how to install Iceweasel 4? I followed the instructions on www.geticeweasel.org (apt-get update && apt-get install iceweasel), but the terminal gives me the following message:

=======
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
iceweasel : Depends: xulrunner-2.0 (>= 2.0) but it is not going to be installed
E: Broken packages
=======

What do I do this fix this? Also, will Iceweasel 4 totally replace my current version 3.5.17? Isn't it possible to have it installed separately so I can still keep my previous version?

I do NOT want Firefox 4, just Iceweasel, thank you.

I used this procedure on
http://mozilla.debian.net/

However I ignore the key.
actual procedure I used:

1. add the following entry in /etc/apt/sources.list

deb http://mozilla.debian.net/ squeeze-backports iceweasel-4.0

2. Open Synaptic, reload, search iceweasel, I can see the installed version 3.x, and the 4.0-1 version in the repos.
3. then I click the iceweasel, Mark for reinstallation, Apply, all the dependencies will be installed.

Yes you can have both versions see:
glandium.org » Blog Archive » Iceweasel 4.0 beta 1 preliminary packages for Debian, and a nice trick : http://glandium.org/blog/?p=1032

The version in Debian experimental is newer than the version at mozilla.debian.net

Personally I upgraded Iceweasel and left Firefox at the current 3.6.16.

Firefox: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.2.16) Gecko/20110319 Firefox/3.6.16

$ apt-cache policy iceweasel

Thanks craigevil for the procedure using experimental

What do I do this fix this?

You need to upgrade your libcairo2. It's up there in the mozilla.debian.net repository. You may have to install it manually.

Go to http://mozilla.debian.net/dists and choose the distro you are tracking (i've pinned mine to Debian Stable/Squeeze for the time being) then the iceweasel-4.0 directory, then your architecture and download the libcairo2_1.10.2-1.1 package. For instance the Debian Squeeze x64 version is located here.

Install it using the terminal command

Code: Select all

sudo dpkg -i Downloads/libcairo2_1.10.2-1.1*

Then follow the commands from mozilla.debian.net to install Iceweasel 4.0.

I held off on installing for a while because the Debian libcairo2 packages don't usually contain the Ubuntu patches that give nice font rendering, but after some research it seems that Debian now does include them and, indeed, after installing Iceweasel 4.0 my fonts render as nicely as ever.

Also, will Iceweasel 4 totally replace my current version 3.5.17? Isn't it possible to have it installed separately so I can still keep my previous version?

It should replace the existing Iceweasel version. The LMDE version of Firefox (3.6.13) wont be affected although you can't run them at the same time.

Thank you all for the replies. I have succesfully installed IW4 just by following the instructions on debian.net after first upgrading libcairo2.

I have been using IW4 for a few days now, and I think I'm going to restore a disk image of my LMDE partition with IW3 because this new IW4 is soooo slow it's just not bearable. To make things worse, also Icedove has become much slower than before. It's not very fun to have to watch windows being drawn on the screen when you click on a link or an article in Icedove.

I admit I am thinking about switching back to Windows because Mint just never gives me the same "snappiness" like Windows does, and this latest experience with IW4 only made things worse.

It's actually funny when you think about it: Windows 7 runs very smooth and fast on my machine, but Mint (or any other Linux distro) always manages to slow things down terribly, even with 2 Gb ram at its disposal.
