Python 2.7 not working anymore: cannot import name md5

Question

I installed python 3.6.3 on my server yesterday (ubuntu 14.04), and now I cannot run python 2.7 (in the virtual envs and on the 'main env').

I've been looking around google for this, without success.

I tried to re-intall openssl as I red.

Can anyone help me ? I'm going mad.

---> Here is the message whenever i tried to execute a python script (or pip):

Solution 1

I had the same problem on macOS.

brew reinstall python@2 solved this problem.

Maybe you could try to reinstall python.

Solution 2

In this post might be a solution:

The python2.7 package is dependent to the libssl1_0_0 package (openssl_1.0 runtime librairies).

So you need to install it, and add the /usr/local/ssl/lib directory in $LD_LIBRARY_PATH environnent variable.
