Help
1

I get this error after the latest Apache update on Ubuntu 16.04 and letsencrypt 0.4.1.

Command: certbot-auto --apache -d example.com

Do i need to reinstall certbot?

Error: couldn't get currently installed version for /root/.local/share/letsencrypt/bin/letsencrypt:

I am getting the same error when I ran ./letsencrypt-auto -v

~/letsencrypt # ./letsencrypt-auto -v

ImportError: No module named datetime

Is there anything we need to do?

Thanks!

hi @dfsgdsfhf and @stevepop

A) This is a help request not a server request
B) From the error messages it looks like date time was not installed on your python system

You can test this by doing the following

python
import datetimie
today = datetime.date.today()
print today

Please paste a screenshot of the result. If everything works you should get something like the image below.

Hi @ahaw021,

Thanks for your response.

As requested here is the screenshot on my server

So I guess datetime was installed in my system after all?

I would suggest reinstalling certbot
