1.4. Configuration
| Ubuntu 18.04 and later has only python3 installed. There is no python command anymore, only a python3 command. Because of that, the following configuration is questionable and should probably be skipped. |
On Debian 8 the python command links to Python 2.
On Debian 9 the python command links to Python 2.
On Debian 10 the python command links to Python 2.
On Ubuntu 17.04 the python command links to Python 2.
On Ubuntu 18.04 there is only a python3 command.
After this configuration the python command links to Python 3.
