I tried to install the ia32-libs as explained, but it is not included in the ubuntu realm anymore. For installing this we need previously to add a new repo:

sudo -i��

cd /etc/apt/sources.list.d echo "deb http://old-releases.ubuntu.com/ubuntu/ raring main restricted universe multiverse" >ia32-libs-raring.list

��apt-get update

��apt-get install ia32-libs

Ok, this may be useful to anyone that is in the same problem, but now i am wondering if we should not addit some how in the pharo ppa, since it looks to be deprecated. Maybe i am wrong, but if it will be deprecated we need to care about this and about the fact that the installation is not straight forward .
