Flashplayer Debugger on a (headless) 64-bit Ubuntu 14.04 Server

To be able to run Flashplayer tests on a 64-bit Ubuntu 14.04 Server instance, one must be able to run Flashplayer Standalone Debugger. This is kind of hard, as Flashplayer Debugger on Linux is 32-bit and ia32-libs has been removed on Ubuntu 14.04.

Short version:

sudo dpkg --add-architecture i386

sudo apt-get update

sudo apt-get install xvfb libcurl3:i386 libglib2.0-0:i386 libx11-6:i386 libxext6:i386 libxt6:i386 libxcursor1:i386 libnss3:i386 libgtk2.0-0:i386

Long version:
The first step is to download the Standalone Flashplayer Debugger from Adobes home page. I put it in /opt/flash.

The first step is to add the 32-bit architecture to be able to download and install 32-bit libraries:

sudo dpkg --add-architecture i386

Then update:

sudo apt-get update

To be able to run the flashplayer headless, we have to install xvfb:

sudo apt-get install xvfb

Install the libcurl3:i386 package, as it is needed, and to get some relevant output from the flashplayer when trying to run it:

sudo apt-get install libcurl3:i386

So, we got the architecture in place. Now we try to run the Flashplayer:

/opt/flash/flashplayerdebugger

It fails with the following output:
./flashplayerdebugger: error while loading shared libraries: libgthread-2.0.so.0: cannot open shared object file: No such file or directory

Now, to locate in which package this file resides, we can use:

dpkg -S libgthread-2.0.so.0

which outputs

libglib2.0-0:amd64: /usr/lib/x86_64-linux-gnu/libgthread-2.0.so.0

libglib2.0-0:amd64: /usr/lib/x86_64-linux-gnu/libgthread-2.0.so.0.4000.0

To install a 32-bit version of this package, we type:

sudo apt-get install libglib2.0-0:i386

Repeating the procedure we find a list of packages to install.

sudo apt-get install libx11-6:i386 libxext6:i386 libxt6:i386 libxcursor1:i386 libnss3:i386 libgtk2.0-0:i386

Now the standalone Flashplayer should be runnable!
