Ranger fails to start due to screen dependency

[GoomerkO]

In a fresh Ubuntu 20.04 install, I installed ranger package.

The first run of the ranger command fails with the following error:

ranger version: ranger 1.9.3
Python version: 3.8.5 (default, Jul 28 2020, 12:59:40) [GCC 9.3.0]

FileNotFoundError: [Errno 2] No such file or directory: 'screen'

After installing the screen package everything just works, so I guest the screen package should be in the ranger's depends list.
