Degrade FEniCS from v.1.2.0 to v 1.1.0

Asked by Xujun Zhao

Hi all,

I didn't notice that my Ubuntu automatically update the FEniCS package from 1.1.0 to the most current 1.2.0. But many of my codes were developed based on FEniCS 1.1.0. Is there a way for me to degrade the package back to 1.1.0 version? Or another way in my mind, first using
sudo ppa-purge ppa:fenics-packages/fenics
to restore everything back to the default packages from the standard Ubuntu archive, which is 1.0.0 , then upgrade to version 1.1.0. Anyone can tell me how to get it?

Thank you very much.

Yes, let me answer my question by myself.
first, remove the latest version. sudo ppa-purge ppa:fenics-packages/fenics
then, update to version 1.1.0
sudo add-apt-repository ppa:fenics-packages/fenics-1.1.x
sudo apt-get update
sudo apt-get install fenics
sudo apt-get dist-upgrade

v 1.1.0 comes back!!
