I ran into an issue today when I could not install
certbot-auto on a Linux
machine running CentOS 6.10.
As it turns out that you need to enable EPEL package repository with yum package manager. The error I got during certbot installation(prior to enabling the EPEL) was:
Package ca-certificates-2018.2.22-65.1.el6.noarch already installed and latest version Package python-devel-2.6.6-68.el6_10.x86_64 already installed and latest version No package python-virtualenv available.

let's focus on the line with
No package python-pip available..
It turns out that python-pip & python-virtualenv are EPEL packages.
These are the packages that caused the issue, because certbot could not install them without EPEL enabled.
Install and enable EPEL:
yum install epel-release -y
Open epel config
[EPEL] ... #enabled=0 enable=1
Save & Exit the text editor. Update packages:
Verify that EPEL was enabled:
yum repolist | grep epel
If grep matches something similar:
# epel Extra Packages for Enterprise Linux 6 - x86_64 12,568
then certbot prerequisites should be met. You can now continue with Encrypt's certbot installation.
