I've just experienced the same issue with installing python3.7.3 on ubuntu18.04. Following this message and running:

sudo apt-get install build-essential libsqlite3-dev sqlite3 bzip2 libbz2-dev \ zlib1g-dev libssl-dev openssl libgdbm-dev libgdbm-compat-dev liblzma-dev libreadline-dev \ libncursesw5-dev libffi-dev uuid-dev 

Allowed me to successfully run sudo make altinstall.

I had the same issue using Ubuntu and the two top answers did not work. I used the answer I got from and tried again and it worked. basically I did:

sudo apt-get install -y make build-essential libssl-dev zlib1g-dev libbz2-dev \ libreadline-dev libsqlite3-dev wget curl llvm libncurses5-dev libncursesw5-dev \ xz-utils tk-dev libffi-dev liblzma-dev python-openssl git 

and then:

sudo make altinstall 

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 .

 echo "deb-src bionic main" >> /etc/apt/sources.list 

2.- sudo apt update

3.- Install python deps

sudo apt-get build-dep python3.6 

Now you can run make altinstall

You can read more details at .

Installing following dependencies will solve the issue:

sudo apt install build-essential zlib1g-dev libncurses5-dev libgdbm-dev libnss3-dev libssl-dev libreadline-dev libffi-dev wget
