Can not launch it on system python version 3.8
and on anaconda as well

System information

- Operating System: Ubuntu 20
- Architecture: x64 (64-bit)
- `act` version: 0.2.25

Expected behaviour

Job launched

Actual behaviour

``` Working directory '/home/alex/projects/proj' | Start installing dependencies | 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 install python3.8-venv | | You may need to use sudo with that command.

python3 -Im ensurepip --upgrade --default-pip
ensurepip is disabled in Debian/Ubuntu for the system python.

Python modules for the system python are usually handled by dpkg and apt-get.

    apt install python3-<module name>

Install the python3-pip package to use pip itself.  Using pip together
with the system python might have unexpected results for any system installed
module, so use it on your own risk, or make sure to only use it in virtual
environments.

UPD: Disregard please:

problem was in missing
apt update command
