Question

PostgreSQL

Unable to install psycopg2 to work with Postgresql in Django. There is a virtual environment with python 3.4, pip install psycopg2 gives You need to install postgresql-server-dev-XY for building server-side extension or libpq-dev for building a client-side application.
I tried, as recommended, to enter sudo apt-get install libpq-dev, it seems to help, but this thing is not installed for me, it finds a bunch of unmet dependencies, and writes that it is impossible to fix, you supposedly have broken packages. I try to install them manually, he again finds some dependencies unsatisfied, ad infinitum.
I have not seen anything about postgresql-server-dev anywhere, but the sudo apt-get install postgres-server-dev-XY command does not work.
