Make sure these boxes are checked before submitting your issue - thank you!

• I have checked the superset logs for python stacktraces and included it here as text if any
• I have reproduced the issue with at least the latest released version of superset
• I have checked the issue tracker for the same issue and I haven't found one similar

Superset version

0.18.5

Expected results

should be success to add new database in webui

Actual results

failed to add new database due to error: "/lib64/libssl.so.10: version `OPENSSL_1.0.2' not found"

Steps to reproduce

• download superset and its dependencies using pip in another machine
• copy the packages to target machine( which is a customed distribution based on centos, the kernel version is 3.10.104-1)
• create venv(python2.7) and install superset in offline mode(just because the target machine couldn't connect to internet)
• start superset and add new database in webui, and get the error, detailed in attachment. The error can be briefed as when executing the statement "from cryptography.hazmat.bindings._openssl import ffi as _ffi", there's an import error "ImportError: /lib64/libssl.so.1.0.0: version `OPENSSL_1.0.2' not found (required by /data/home/tbds/venv/lib/python2.7/site-packages/cryptography/hazmat/bindings/_openssl.so)". Try much but couldn't find the reason. Also didn't find similar answers in google.

You have built cryptography for openssl 1.0 but it's not there anymore. Have you upgraded distribution in the mean time? Also unrelated to superset, please close.
