Certbot not running in nginx on ubuntu 18.04

Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. https://crt.sh/?q=example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

My domain is:
api.homadorma.com
I ran this command:
sudo certbot --nginx
It produced this output:
Saving debug log to /var/log/letsencrypt/letsencrypt.log

Plugins selected: Authenticator nginx, Installer nginx

An unexpected error occurred:

TypeError: init() got an unexpected keyword argument ‘cert_file’

Please see the logfiles in /var/log/letsencrypt for more details.

My web server is (include version):
nginx
The operating system my web server runs on is (include version):
ubuntu 18.04
My hosting provider, if applicable, is:
AWS
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
The version of my client is (e.g. output of certbot --version or certbot-auto --version if you’re using Certbot):
certbot 0.31.0

Further note:
The ssl is currently set up manually using certbot-auto. The thing with certbot-auto is that the auto renewal does not work.

It seems that fixing the autorenewal might be easier than probably uninstalling and reinstalling certbot.
But that’s your call.

Towards an auto-renewal fix:

  • please show the current renewal conf file for the cert in question.

Towards fixing certbot:

  • How (exactly) was it installed ?
    [some of the directories shown don’t seem correct]
  • Run a complete “sanity” check:
    sudo apt-get install debsums
    sudo debsums | grep -v OK
    sudo debsums -s
    [these may take a few minutes]
  • reinstall certbot:
    sudo apt-get install python-certbot-nginx
  • compare your packages with my Ubuntu 18.04 certbot +nginx package list:

I haven’t looked into the specifics, but…

I guess the urllib3 Python module installed in /home/ubuntu/ is incompatible with something else. Maybe it’s too new, or too old, or broken somehow.

Do you know why it’s installed, and what version it is?

If you run “sudo -H certbot --nginx”, it may work around whatever’s happening, since it will set HOME to /root and Python may be less likely to find modules in /home/ubuntu.

Edit: Googling the error, it’s probably requests and urllib3 that are incompatible.

Thanks. sudo -H certbot --nginx works. No error reported this time.

I then tested renew. I ran sudo certbot renew --dry-run, same error.
I ran sudo -H certbot renew --dry-run, passed. So I believe I should change the way the renew command is run.

I ran crontab -e, found this line:
0 0 * * 0 sudo certbot renew

My understanding is that if I change it to 0 0 * * 0 sudo -H certbot renew, the renew should work.

Is my understanding correct?
