Hi,

I'm using Ubuntu 20.04.02 LTS and having issues with certbot. For a few weeks, I cannot renew my certificates.

CLI: certbot certonly --manual --preferred-challenges dns -d \*.soc-bd.nl -d soc-bd.nl

I get the following error log:  
aving debug log to /var/log/letsencrypt/letsencrypt.log  
Plugins selected: Authenticator manual, Installer None  
An unexpected error occurred:  
Traceback (most recent call last):  
File "/usr/lib/python3/dist-packages/requests/models.py", line 379, in prepare\_url  
scheme, auth, host, port, path, query, fragment = parse\_url(url)  
File "/usr/lib/python3/dist-packages/urllib3/util/url.py", line 392, in parse\_url  
return six.raise\_from(LocationParseError(source\_url), None)  
File "", line 3, in raise\_from  
urllib3.exceptions.LocationParseError: Failed to parse: [https://acme-v02.api.letsencrypt.org/directory](https://acme-v02.api.letsencrypt.org/directory)

During handling of the above exception, another exception occurred:

requests.exceptions.InvalidURL: Failed to parse: [https://acme-v02.api.letsencrypt.org/directory](https://acme-v02.api.letsencrypt.org/directory)  
Please see the logfiles in /var/log/letsencrypt for more details.

Any idea what could be wrong? I have reinstalled urllib3 and certbot. Doesn't clear the issue.

Regards,  
Karl

From searching around, it looks like it might be a problem with the `python3-six` package.

Perhaps try:

```
sudo apt install --reinstall python3-six
```

Did the reinstall. Didn't fix the issue.  
wget [https://acme-v02.api.letsencrypt.org/directory](https://acme-v02.api.letsencrypt.org/directory) is working fine. So the site is reachable.

Well, if I read the code for [`parse_url()`](https://github.com/urllib3/urllib3/blob/73c7e0356d90e5a4618f11faeb86b0b36d24e9d8/src/urllib3/util/url.py#L337-L439) correctly, the exception is raised on any `ValueError` or `AttributeError` in the `try:` block, which contains 24 lines of code.

However, without being able to reproduce the error, it's rather hard to debug it locally I'm afraid.

Fixed the problem. I have install certbot via apt install certbot. This version was causing the problem. The snap install version is ok. I will open a cause with Ubuntu.

Thanks for your support.

I think the snap version of certbot comes with the Python dependencies embedded in the snap, so that would indeed fix this issue, but just for certbot. Other packages/applications might suffer from the same bug.
