Cannot start venv with python3

When trying to start a virtual environment I get:

~$ python3 -m venv homeassistant The virtual environment was not created successfully because ensurepip is not available. On Debian/Ubuntu systems, you need to install the python3-venv package using the following command. apt-get install python3-venv You may need to use sudo with that command. After installing the python3-venv package, recreate your virtual environment. Failing command: ['/home/gal/homeassistant/bin/python3', '-Im', 'ensurepip', '--upgrade', '--default-pip'] 

But when I try to install python3-venv I get:

~$ sudo apt-get install python3-venv Reading package lists... Done Building dependency tree Reading state information... Done python3-venv is already the newest version (3.6.7-1~18.04). 0 upgraded, 0 newly installed, 0 to remove and 38 not upgraded. 

I should have several python versions installed but I remove them as alternatives:

~$ sudo update-alternatives --config python3 There is only one alternative in link group python3 (providing /usr/bin/python3): /~$ sudo update-alternatives --config python3 There is only one alternative in link group python3 (providing /usr/bin/python3): /usr/bin/python3.7 Nothing to Nothing to configure. 

Python version is 3.7.5:

~$ python3 --version Python 3.7.5 

OS version is:

~$ lsb_release -a No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 18.04.4 LTS Release: 18.04 Codename: bionic 

I think that the problem is becuase of 'python3-venv is already the newest version (3.6.7-1~18.04).' while the version I use is 3.7 and not 3.6. But I don't know how to proceed.

Thanks for any suggestions.

You can install a venv for your version of python.
