Description

I upgraded my computer and it seems that it completly remove /usr/bin/python.
I downloaded the last version and run the installer but didn't fix it. I ended up editing the executable and changing the shbang to /usr/bin/python3 and now it is working :)

I understand this is a free project but why this is invalid?
Ubuntu does not have /usr/bin/python and your code has so it is a bug.
/usr/bin/env python /usr/bin/env: ‘python’: No such file or directory

[remitamine]

youtube-dl support both python 2 and python 3, so /usr/bin/python3 should not be hardcoded, instead, you can provide the /usr/bin/python file in you're distribution(symlink) or install python 2(it will provide the /usr/bin/python file).

Note that Ubuntu (20.04 and after) doesn't have python command until you install either "python-is-python2" or "python-is-python3"
(source: https://wiki.ubuntu.com/FocalFossa/ReleaseNotes#Python3_by_default, and /usr/bin/python is not present by default on any new installs)

The command to fix this is
sudo apt install python-is-python3
(or change python3 to python2 if you prefer Python 2 more)
