Cannot find Apache control command apachectl,Python 2.6 is no longer supported by

Hi ,

I am trying to install Let’s Encrypt Cert using Centos6/Apache on hosting provider Vultr. For the domain

I am using the guide from the following link for install steps;

During the setup I

This is the first time I have run a server , I have had a look at some suggested fixes but they vary and I rather not make a mistake. Can someone help me work a solution for this ?

Thanks all!

There may be an issue with certbot 0.17 and python 2.6…
Can you update the python to 2.7?

Hi thanks for the reply. As I mentioned first time using a server so all new to me. I had a look around re: update python 2.6 to 2.7 on Centos 6.3 and the guides vary a little to a lot. Most with warning if not done right you might break yum. Any suggestions on a guide that is good of how to do this would be helpful.

Thanks again

Hi again,

Most of the guides I found a very long. I have come across the guide which seems pretty straight forward , not sure if its correct though.

Any thoughts on if that guide would do the trick ?


if you aren’t using python for any other purpose - certbot only.
then it’s safe to remove it and try certbot-auto (which should load/install all requirements)

if that fails, try
apt-get update
apt-get install python
yum -y update
yum install -y python27

I believe CentOS (and many other Linux flavors) rely heavily on Python, and modifying the system Python can be an issue. You can install multiple versions alongside each other, however.
