certbot-auto doesn't work on RHEL 8

[bmw]

This was reported by @haidarvm at #7202 (comment).

My operating system is (include version):

RHEL 8

I installed Certbot with (certbot-auto, OS package manager, pip, etc):

certbot-auto

I ran this command and it produced this output:

sudo /usr/local/bin/certbot-auto  --debug --nginx --verbose

@haidarvm, I think the problem is it's looking for the executable virtualenv in your PATH and can't find it. Solving that problem should fix it.

I don't have easy access to a RHEL 8 machine right now to test it, but I think the executable is in the python3-virtualenv package.

[haidarvm]

@bmw Thanks a lot for the support, it's so simple by adding :
$ sudo dnf install python3-virtualenv

And Everything runs fine and smooth 👍 here's the result :
sudo /usr/local/bin/certbot-auto --nginx --verbose --debug
