libgtk-x11-2.0.so.0:i386 not available on Ubuntu 13.10 64 bit; troubles with Adobe Air

Question

I've been trying to install Adobe Air on my 64 bit Ubuntu machine. The first thing I tried was to follow this tutorial that symlinks the missing libraries, but it is under the impression that HAL was still available, so I then had to follow this guide to get HAL working. Now my issue is that when I try to run ./AdobeAIRInstaller.bin, it tells me that it can't find libgtk-x11-2.0.so.0 because of 13.10's folder structure (libraries aren't simply in /usr/lib anymore, they're sub-foldered by build). I then tried to make a symlink from /usr/lib/x86_64-linux-gnu/libgtk-x11-2.0.so.0 to /usr/lib/libgtk-x11-2.0.so.0, but lo and behold, we need it to be a 32 bit library, says the linker:

/tmp/air.RYKQLa/setup: error while loading shared libraries: libgtk-x11-2.0.so.0: wrong ELF class: ELFCLASS64

I can't seem to find the package libgtk-x11 in Synaptic, and sudo apt-get install libgtk2.0-0:i386 didn't get the right library. Is there a way around this or a way to get libgtk-x11-2:i386? Thank you in advance!

Solution

Since you said libgtk-x11-2:i386 is installed (via apt, which doesn't lie, usually), you should symlink to /usr/lib/i386-linux-gnu/libgtk-x11-2.0.so.0:

cd /usr/lib
rm ./libgtk-x11-2.0.so.0
ln -s /usr/lib/i386-linux-gnu/libgtk-x11-2.0.so.0

Is libgtk2.0-0:i386 installed? It is if find -name /usr/lib 'libgtk-x11-2.0.so.0' 2>/dev/null returns something.

Yeah, I already tried that.

I know I already installed it through apt-get, but it didn't include libgtk-x11:i386. I can't even find the package on Synaptic.

Nonono, only the 32 bit version is installed. Miraculously, the 32 bit version appeared out of thin air, though. I wish that I could have found how I solved the problem.

Synaptic only deals with the package names, and doesn't pay attention to the architecture suffix (:i386 and :amd64), like apt can.
