I recently tried installing Salome un my Ubuntu 12.10, using these instructions http://code-saturne.blogspot.ro/2010/05/installation-of-salome-513-on-ubuntu.html
and as soon as i installed ia32-libs things took a bad turn. The terminal crashed and now it only displays the $ sign, and whaterver command i type it doesn't work. In addition, whenever ubuntu tries to update i get errors when trying to install packages.
If there's need for more information, i'll try to provide it, although i've only recently migrated to linux from windows.
Thank you very much!
