Thanks Lawrence, I am not sure if this is exactly what you meant but I tried this and have the following output. Unfortunately, the updating does not get any better.

Hello,

I have tried updating firedrake for the first time in months but it seems to fail. The output suggests doing a firedrake-clean, which I have tried but that seems to have failed. I am attaching the log file.

Can anyone suggest something that I might be able to try to get this working?

It looks like basically everything worked, but firedrake-clean failed. Can you try running that on its own in an activated venv? Cheers, Lawrence _______________________________________________ firedrake mailing list firedrake@imperial.ac.uk https://mailman.ic.ac.uk/mailman/listinfo/firedrake

Yes, when I try importing firedrake things go badly. See below. (firedrake) fpoulin@amlt21:~/Desktop/Talks/10-ExperientialLearning/Notebooks$ python Python 3.6.5 (default, Apr 1 2018, 05:46:30) [GCC 7.3.0] on linux Type "help", "copyright", "credits" or "license" for more information.

OK this was successful. I think, if I read the output correctly, that your firedrake-update step did complete successfully. Other than the final error message about firedrake-clean failing, was there any other reason you thought it had not?
