That sounds like other and severe problems. It would perhaps be better 
to fix that first.

We don't know how you installed Kallithea before, but you must have been 
using a py3 pip. Weird it doesn't pick that one up now. Something weird 
is going on.

It seems like you ended up using the last "Installing a released version 
without virtualenv" options on 
https://kallithea.readthedocs.io/en/stable/installation.html . I had 
forgotten we mention these in the documentation. That doesn't get much 
testing. A Kallithea specific virtualenv has the advantage of keeping 
everything installed for Kallithea in one place, separate from things 
that might be installed for other reasons.
