Installing flownet

[tayloris]

As far I see, the SSL Error is on the pip installations. I can solve the problem for the installation of LIBECL, LIBRES but I done manage to install ERT. I downloaded the ERT repository and change the line that call pip install ... to the corresponding pip install --trusted-host pypi.org --trusted-host files.pythonhosted.org <package>, but that didn't work. There should be a simple solution but I have not found it yet.

pypa/pip#5288

This is of course unrelated to FlowNet, but I guess the reason is that somewhere (maybe in openssl), security level has recently been tightened, without everything in the Python pip world following up (as of now).

This question is probably related: https://askubuntu.com/questions/1233186/ubuntu-20-04-how-to-set-lower-ssl-security-level

Note that I would guess trusted-host basically bypasses https / SSL verification, and therefore opening up for man-in-the-middle attacks, and thus not a recommended solution.

What is the pip and openssl versions?

[tayloris]

The versions are: pip 20.1.1, and OpenSSL 1.1.1f 31 Mar 2020

It happens as well on a new installation of Ubuntu 18.04 :( . It is strange because it works on my laptop that is Ubuntu 18.04 but not in the PC :(.

Not sure what is the easiest, and still secure, way of solving this. A search on the Internet indicates that this is a quite new mismatch between pip and OpenSSL, and will probably be solved externally at some point.

I guess we close this issue here since it is unrelated to FlowNet, but we can still continue the discussion in the closed issue if needed.
