I was following a tutorial and this was the error.

Welcome to Python 3.6's help utility!

as you can see it works, but I am unsure about future uses. thanks for any guidance.

Use the following commands in this order:

1. ./configure


2. make clean


3. make


4. sudo make install

Just in case somebody reads this thread, the issue is actually that a dependency is missing. In this case, zlib headers.

Basically, you must:

1.- Enable the deb-src http://archive.ubuntu.com/ubuntu/.

I.e echo "deb-src http://archive.ubuntu.com/ubuntu/ bionic main" >> /etc/apt/sources.list

2.- apt update

3.- Install python deps
apt-get build-dep python3.6

Now you can run "make altinstall"
