Cryptography: 1.0.1t-1+deb8u2 causing compilation failures "error: ‘SSLv2_method’ redeclared as different kind of symbol"

Created on 9 Jun 2016  Â·  11Comments  Â·  Source: pyca/cryptography

Reported this to Openssl and was advised issue is with Python.

https://github.com/openssl/openssl/issues/1190

On Debian 8.4, Linux ip-10-1-1-99 3.16.0-4-amd64 #1 SMP Debian 3.16.7-ckt25-1 (2016-03-06) x86_64 GNU/Linux

Since upgrading from 1.0.1k-3+deb8u5 -> 1.0.1t-1+deb8u2 I cannot install pip cryptography 1.0.1 *

Reproduce

apt-get install --force-yes libssl-dev=1.0.1t-1+deb8u2 libssl1.0.0=1.0.1t-1+deb8u2 openssl=1.0.1t-1+deb8u2 build-essential python-pip python-dev libffi-dev
pip install cryptography

Workaround

apt-get install --force-yes libssl-dev=1.0.1k-3+deb8u5 libssl1.0.0=1.0.1k-3+deb8u5 openssl=1.0.1k-3+deb8u5
pip install cryptography

Force installing the previous version of openssl resolves the issue. *

It is easily reproduced with the packages / pip install cryptography.

I've debugged:

    text = '\n'.join(complete_log)
UnicodeDecodeError: 'ascii' codec can't decode byte 0xe2 in position 59: ordinal not in range(128)

And determined the encoding of my provisioner or shell has no effect and has always been set UTF8.

It looks like this may be the cause (caveat, I know zero C):

Unfortunately it's somewhat expected that older cryptography's will not work with newer OpenSSLs. Unless anyone can reproduce this issue with 1.4, I don't think there's anything to do here?

Experiencing this same issue. Totally get that it's open source and such, but poking it as I'm curious how soon a fix would be available.

Is the traceback you provided from cryptography 1.4? I don't see any of the SSLv2 lines it indicates in our present source code.

alex picture alex on 10 Jun 2016

As a data point, I just upgraded our jessie builder to 1.0.1t-1+deb8u2 and did pip install cryptography in a virtualenv without any issues.

reaperhulk picture reaperhulk on 10 Jun 2016

@alex, The issue initially occurred in cryptography==1.0.1
It also occurs in the latest pip installable version (1.4)

I probably pasted you 1.0.1

russmac picture russmac on 10 Jun 2016

@reaperhulk So you wernt able to without a vritualenv but were with? Could you try without a vritualenv?

russmac picture russmac on 10 Jun 2016

@russmac Can you provide a traceback from 1.4?

alex picture alex on 11 Jun 2016

I was able to install 1.4 on a fresh build today without producing the issue. Was able to reproduce it for cryptography==1.0.1 only.

Time for me to report issue to the project using it. I hope they like Debian.
