Unable to run certbot or letsencrypt because of a ValueError (new_authzr_uri)

Help

My certificate expired. I had obtained a certificate last time for www.musicwhim.com
So I figured I could delete the expired certificate and obtain a new one for musicwhim.com without the www. There was some error while creating a new certificate, so I decided to update certbot. After updating, certbot/letsencrypt fails to run at all. I’ve pasted the error below.

My domain is: musicwhim.com

I ran this command: sudo certbot --apache

It produced this output:

Traceback (most recent call last):

My web server is (include version): apache2

The operating system my web server runs on is (include version): Ubuntu 16.04.4 LTS (xenial)

My hosting provider, if applicable, is: -

I can login to a root shell on my machine (yes or no, or I don’t know): Yes

I’m using a control panel to manage my site (no, or provide the name and version of the control panel): No

Please show:
certbot --version
certbot certificates
grep -Eri 'servername|serveralias' /etc/apache2

How did you delete the cert?

How did you update certbot?

(since they both go to the same IP)
You can get a cert that holds both names.

I used certbot delete

I completely uninstalled it and then installed it using the steps from the certbot site.

Turns out, there was an older version of certbot installed using pip (probably a long time back) and that was causing this problem.

I just updated this certbot using pip and it seems to be working fine.

Thanks for the help!
