Ubuntu 20.04 without python-as-python3 apt package errors No such file or directory: 'python'

See original GitHub issue

I am on the latest Poetry version.
I have searched the issues of this repo and believe that this is not a duplicate.
If an exception occurs when executing a command, I executed it again in debug mode (-vvv option).

OS version and name: Ubuntu 20.04
Poetry version: 1.1.8

In ubuntu 20.04 there is not “python” command, only “python3”. If I install sudo apt-get install python-is-python3, then poetry starts to work again.

It would be nice if poetry picked python3 if there is no python instead of failing. There is a python installed.

Thanks for your response! I’m able to reproduce it. It seems to be due to a change in poetry 1.1.8. I have no problems with 1.1.7. I guess https://github.com/python-poetry/poetry/issues/4414 is somehow related.
