Re: [FEniCS-support] Installing FEniCS: urllib failed to download

Thanks Johannes & Jo,

I appreciate your help!  I have successfully installed FEniCS since I sent out 
this request.


A few notes:
-I’m on an OS X system and don’t have the ssl certs stored there. (This would 
be a smart thing to try to do though).
-I still get the error when installing dev or release
-I did get the installation to install and work, mainly by replacing the 
repository URLs with alternatives (attached)
-I don’t remember if I needed to use system python when I compiled, since if I 
remember, it built it’s own python. (Sorry, it’s been a few weeks!)


Thanks again,
Andy

If you are on Linux and get the CERTIFICATE_VERIFY_FAILED error, then you can try to set the SSL_CERT_DIR, for instance:

export SSL_CERT_DIR=/etc/ssl/certs

I just wanted to let you know, that I get the same error for the stable build but seemingly not the dev build.

Best,

Hi Andrew,

Sorry for the late reply.. Are you using the standard system Python?

Hello,

I have a question similar to this one: http://fenicsproject.org/qa/7318/dolfin-error-urllib-failed-to-download , where urllib is failing to download
packages. I’ll get a message like the following:

Downloading
https://pypi.python.org/packages/source/J/Jinja2/Jinja2-2.7.3.tar.gz...

[ERROR] urllib failed to download (reason: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:590)):

https://pypi.python.org/packages/source/J/Jinja2/Jinja2-2.7.3.tar.gz

[CRITICAL] You may wish to check your Internet connection or the remote server

If it matters, I’m using OS X 10.10.3 installing using fenics-install.sh . I find that I can get around this error by following the instructions at that linked help page (namely to find a different link for the package and substitute that in the
yaml file), but it’s happening to so many packages, that I worry that this might take days to do them all.

(And FWIW, I do have an internet connection.)

It sounds like this is an error on my system or configuration… something that I can easily fix by doing some sort of SSL certificate update? But I’m not sure where to start.

Thanks for any insight you can provide!
