Youcompleteme: Error with python setup, no module named pyasn1.type

[kb100]

After compiling the ycm support libs (I followed the instructions for not caring about semantic support for C-family languages), opening vim gives the error before opening.

Running debian stretch
Python version is 2.7.10
Vim version is 7.4 with python support
I've checked and I have python-pyasn1, python-pyasn1-modules installed, so I don't see why thiscould be happening, but the error indicates that it might use plain HTTP instead of HTTPS so that sounds very bad.

Weird, for some reason the pyasn1 files were missing even though the package was installed, fixed with sudo apt-get --reinstall install python-pyasn1 python-pyasn1-modules
