Hi, I have successfully run my own python code (ipython) in Fenics with Ubuntu 12.0.4 for the past year. I just upgraded the OS to Ubuntu 14 last month. Afterwards, I did apt-get to reinstall fenics, along with the ppa installation commands according to the Fenics website. However, I can't run any .py programs that 'import dolfin' (mine or the demos). (I can run .py programs using mayavi to visualize old results.) Do I need to run any specific dolfin installation commands to make sure I'm using the latest (version 1.4)? The crash when I'm running seems to be from calling a dolfin XML file in the demos folder - this XML is from 2011 (the same file I have on my Ubuntu 12 computer). I'm hoping there's an easy installation command... Or do old Fenics/dolfin installations need to be un-installed/re-installed after an OS upgrade?
Thank you! David
