"Try installing just pharo-launcher (without :i386). The handling of 32bit packages within a 64bit environment was changed in ubuntu. I don't know the details, but I installed pharo-launcher in ubuntu 14.04 yesterday and it just works fine.
If you can confirm, maybe the respective community page should be updated to reflect this change." no idea how to install without i386 sudo apt-get install pharo-launcher just tells me that i386 pharolauncher is already installed. Note that I have Ubuntu 13 and not 14. So what applies for you may not for me or anyone that still uses UBUNTU 13.
