Impacted versions

Modoboa: recent
installer used: Yes

Steps to reproduce

running the installer on a clean system

Current behavior

idna v2.7 got released yesterday. Installer is collecting the new version:
Collecting idna>=2.1 (from cryptography->modoboa) Downloading https://files.pythonhosted.org/packages/65/c4/80f97e9c9628f3cac9b98bfca0402ede54e0563b56482e3e6e45c43c4935/idna-2.7.tar.gz (172kB)

requests 2.18.4 relies on idna being <2.7 and >=2.5
requests 2.18.4 has requirement idna<2.7,>=2.5, but you'll have idna 2.7 which is incompatible.

result of the whole story is that lxml is not installed properly (though i'm not sure, if that is error is occuring because of the idna incompatibility):
Running setup.py install for lxml ... error

EDIT: it seems the lxml-error is independent to the idna compatibility issue above. It is most likely caused by insufficient memory of a Raspberry Pi. So I'm not sure anymore if the idna incompatibility with requests is affecting the install at all.

Expected behavior

no error occurrence at lxml install
