After install

sudo apt-get install ia32-libs-multiarch g++-multilib build-essential
sudo apt-get install libglu1-mesa-dev x11proto-core-dev x11proto-gl-dev x11proto-kb-dev libxxf86vm-dev libasound2-dev libfreetype6-dev libxpm-dev libxft-dev

Question not gone, but game now starts and work fine.

ia32-libs are not a good way to go, you should look at using multiarch.

sudo apt-get install ia32-libs-multiarch g++-multilib build-essential
sudo apt-get install libglu1-mesa-dev x11proto-core-dev x11proto-gl-dev x11proto-kb-dev libxxf86vm-dev libasound2-dev libfreetype6-dev libxpm-dev libxft-dev

These commands are pulling in a bunch of development packages which shouldn’t be needed for Trine 2, the launcher should run Trine 2/bin/install_ubuntu_ia32_libs.sh on first launch, would you be able to add more output from running steam in a terminal, after removing what you installed.

Imagine this is related to sudo use in the script and not a GUI sudo variant.

I also have bought Trine2 on a kubuntu 64 bit and had the same error.

The solution I have used is

1. go to your Home directory by opening the Konsole

2. use command below (quotes "" included)
   cd ".local/share/Steam/SteamApps/common/Trine 2/bin"

3. launch the libraries installation script below
   sudo sh install_ubuntu_ia32_libs.sh

   wait that script completes ... and close the Konsole

4. launch the game from steam again and it should work fine

That doesn't solve the installation bug problem ... but it works ...
... And as john drinkwater commented/suggested these actions should be handled by steam client :

but perhaps the popup :
"Would you like to install them now? This requires your user account to have administrator permissions."

- don't launch anything
- is not able to show you a terminal or gui for handling the sudo sh command
- ... or something else   ...

Well, after run
sudo sh install_ubuntu_ia32_libs.sh
it's work, thx.

But, if this or the similar library installed from other place, and game after that work, should message "Trine 2 Launcher script" popup every time before game start?

I think that the " 'Trine2 launcher' shown at every launch of the game" is normal : it's probably "as designed" by the developers (Frozenbyte) ... I suppose that "Having the ability to change settings before game launch" is a way to prevent "the creation of a bad config file" resulting to a game that won't start anymore (ex "resolution or anti aliasing too big for my graphic card" kind of problem)... It is probably not a bug, it's a feature ;)

@Telekolki, @eoxx just checking through old bugs, does kubuntu have xterm installed? dpkg -l xterm to find out. Pressing yes should open a terminal which is running apt-get and it should ask for a password.

Hi, to answer your question :

"does kubuntu have xterm installed?"

yes it was present when I did the installation of Trine 2

herunder the output of the command "dpkg -l xterm"
