Dear Firedrakers, Some of you have recently had problems with installing PETSc recently. There is now a fix for this, and also new install URLs for PETSc and petsc4py which will hopefully reduce the number of ongoing PETSc install issues that people have. The short version is that the instructions for installing PETSc and petsc4py on our websites have been updated, so if you are installing or upgrading PETSc you should follow the new instructions: http://www.firedrakeproject.org/obtaining_pyop2.html#petsc The ever so slightly longer version is that we now point to our own fork of PETSc rather than the upstream master. We will update our forks as necessary and only after checking that the version we update to appears to work. This should hopefully reduce the number of random breakages users encounter in PETSc.
