hi @Dave123

it looks like certbot it not installed

did you unistall?


How to install certbot ?

Well, that would the ~auto script actually do for you… And it should take care of all dependencies…

But for some reason your datetime Python module could not be found. That’s actually pretty weird, because it’s a built-in module.

There are a few sites which relate to this problem, such as http://askubuntu.com/questions/509283/python-no-module-named-datetime

Try Google for datetime python ubuntu.

I am using this command for renewing the certificate
./letsencrypt-auto renew --dry-run. Can you please help me to understand where to put auto ?

I downloaded using ln -s /usr/lib/python2.7/lib-dynload/datetime.x86_64-linux-gnu.so /usr/lib/python2.7/lib-dynload/datetime.so but its throwing error.
