Hello David, Sorry for bugging you, clearly not a firedrake problem I agree. Not sure why but I had a library missing and the following helped me to resolve it by creating a link http://www.rainlendar.net/cms/index.php?option=com_kunena&Itemid=42&func=vie... Now I am reinstalling firedrake. I imagine things will work better afterwards.

It is true that curl depends on librtmp. If your curl can't find your rtmp, then something is broken on your system. This has nothing to do with Firedrake. I *think* that the only time you use curl is to download the firedrake-install script. If you really can't unbreak curl on your system then you can obtain this script by any of the usual ways (wget, download it with a web browser etc.) Regards, David On Mon, 27 Jun 2016 at 19:35 Francis Poulin <fpoulin@uwaterloo.ca<mailto:fpoulin@uwaterloo.ca>> wrote: Hello David, Thanks for finding that. I tried a) and that didn't help the update. I then tried b) and get an curl error, "error while loading shared libraries: librtmp.so.0". I have done this before but not sure why this is not working now.

I don't know why this was changed but it makes the python binary in your virtualenv incompatible with your system python install. According to the thread on askubuntu, you have two options. a) Apparently you can re-initialise the virtualenv by running: virtualenv . in your top Firedrake directory. I'm guessing you should do this with the virtualenv deactivated. or b) A fresh Firedrake install should work because it will create a fresh virtualenv based on current Python binary.

I tried running firedrake and it failed. I also tried updating firedrake and it failed, see below. Do I need to install it from scratch or should it be possible to update it with a new OS?
