Not sure whether this would be better in "General Support" - please comment if you think so.

I have a new computer which has the amd64 version of Ubuntu 12.04.3 installed. (Also has unity and unity2d removed and gnome-shell installed - I use Gnome Classic.)

I am trying to install FreeWRL (http://freewrl.sourceforge.net/index.html).
So I downloaded the latest:
freewrl_1.22.13-1_amd64.deb
and tried to open it with Ubuntu Software Center. Installing gave the error "Dependency could not be satisfied - libfontconfig1 (>= 2.9.0)"

I then tried it with dpkg


$ sudo dpkg -i freewrl_1.22.13-1_amd64.deb
[sudo] password for :
Selecting previously unselected package freewrl.
(Reading database ... 191413 files and directories currently installed.)

dpkg: dependency problems prevent configuration of freewrl:
freewrl depends on default-jre | java-runtime; however:
Package default-jre is not installed.
Package java-runtime is not installed.
freewrl depends on libfontconfig1 (>= 2.9.0); however:
Version of libfontconfig1 on system is 2.8.0-3ubuntu9.1.
freewrl depends on libglew1.7 (>= 1.7.0); however:
Package libglew1.7 is not installed.
freewrl depends on libimlib2; however:
Package libimlib2 is not installed.
freewrl depends on libmotif4; however:
Package libmotif4 is not installed.
freewrl depends on libmozjs10d; however:
Package libmozjs10d is not installed.
freewrl depends on libnspr4-0d (>= 1.8.0.10); however:
Package libnspr4-0d is not installed.
dpkg: error processing freewrl (--install):

So I downloaded libfontconfig1_2.9.0-7.1_amd64.deb from debian:

sudo gdebi libfontconfig1_2.9.0-7.1_amd64.deb
[sudo] password for bob:

So I downloaded fontconfig-config_2.9.0-7.1_all.deb from debian:

sudo gdebi fontconfig-config_2.9.0-7.1_all.deb

So I tried a trick I learnt from http://forums.codeblocks.org/index.php?PHPSESSID=vdcae2kd3o9fdncos9ru9i4ke2&/topic,17945.0.html and created a folder with both .deb files:

$ sudo dpkg -i *.deb

At this point I don't know what to do next and don't understand why libfontconfig1:i386 is there.

Help.

Trying to install new versions of software on an older system like 12.04 often leads to dependency problems like this.
Perhaps you wish to try an older version of the freewrl package?
An older package may be happy with your older 12.04.3 libfontconfig version.

Another, more drastic option is to upgrade your version of Ubuntu, which will also upgrade libfontconfig. If you are installing new versions of software on your system, you're rather outside the envelope of intended LTS use (stability without changes).

Don't forget to tell this problem to the developer or packager of your problem. Since this package is not in the Ubuntu Repositories, this forum doesn't support it. The developer or packager supports it.
Of course, we'll try anyway.

And if their software is stable, remind them to jump through the final hoop and submit their software to the Debian archive. Then Ubuntu will pick it up automatically and we will support it here.

Thanks for these comments. There were a couple of older versions available. I don't know if these look more promising:

Yes, I'm thinking of looking at 14.04 LTS when it comes out.

I'll do that too.

It looks to me like the Squeeze package should offer the least problems...

Four of the five packages are in the Ubuntu Repositories. One is in Debian's Squeeze archive.

Try installing the Ubuntu dependencies and Debian dependencies before installing the freewrl package. I sure you already know that dpkg -i merely installs the specified package, it doesn't automatically install dependencies.

sudo apt-get install libglew1.5 limilib2 libmotif4 libnspr4-0d
sudo dpkg -i /path/to/libmozjs2d.deb
sudo dpkg -i /path/to/freewrl_1.22.10-1_amd64.deb

Thanks, it installed, even on my damaged system:

sudo apt-get install libglew1.5 libimlib2 libmotif4 libnspr4-0d
sudo dpkg -i libmozjs2d_1.9.1.16-20_amd64.deb
sudo dpkg -i freewrl_1.22.10-1_amd64.deb


Mind you, it crashed, but I wonder if that is because libfontconfig1 is in a mess. If so, it might pay me to re-install Ubuntu again.
