For Developers: There is a huge forum thread in which the creation of the Ubuntu PPA packages was disscussed. It may be usefull if the Ubuntu PPA packages needs to be updated. On Launchpad there are more than one CalculiX packages. Only one CalculiX package should be installed and any of them should work. There is a simple reason for not taking the one which was allready on Launchpad. We did not know about it (see http://forum.freecadweb.org/viewtopic.php?f=18&t=10393&start=90#p85498)
