Help

My domain is:
jinjiusolutions.com

I ran this command:
# sudo certbot --nginx --nginx-server-root /www/server/nginx/conf/

(After ran the command ‘# sudo certbot --nginx’.)

It produced this output:

Hi @evaime

that's the

ç: LATIN SMALL LETTER C WITH CEDILLA

Check your Certbot-config files and your webserver config files.

/usr/lib/python2.7/site-packages/certbot/tests/display/ops_test.py:313:        all_invalid = ["??????ps.net", "uni??od??.com"]
/usr/lib/python2.7/site-packages/certbot/tests/display/ops_test.py:314:        two_valid = ["example.com", "??ni????de.com", "also.example.com"]
/usr/lib/python2.7/site-packages/certbot/tests/display/ops_test.py:327:                                          "uni??od??.com")
/usr/lib/python2.7/site-packages/certbot/tests/display/ops_test.py:352:                                          "uni??od??.com")
/usr/lib/python2.7/site-packages/certbot/tests/main_test.py:1223: names = ['uni **??** od **??** .com']

???

Hello, where’re these Certbot-config files?
Why these packages auto-installed decodes ‘ç’?

5 
# echo $LANG

en_US.UTF-8
6

Check the files in

/etc/letsencrypt/renewal

It's not an UTF-8 coded char. Hex e7 as UTF-8 -> two bytes - %C3%A7

Maybe in a comment.

7

Thanks for your answer. Could you tell me how to resolve the problem?

There is not any files in ./renewal

8

You have already the grep command. Use that to find that file.

9

What are these '_test.py' files using for? Can i just delete the test files directly?

10 
def test_get_valid_domains(self):
        from certbot.display.ops import get_valid_domains
        all_valid = ["example.com", "second.example.com",
                     "also.example.com", "under_score.example.com",
                     "justtld", "*.wildcard.com"]
        all_invalid = ["öóòps.net", "uniçodé.com"]
        two_valid = ["example.com", "úniçøde.com", "also.example.com"]
        self.assertEqual(get_valid_domains(all_valid), all_valid)
        self.assertEqual(get_valid_domains(all_invalid), [])
        self.assertEqual(len(get_valid_domains(two_valid)), 2)

Parts of the file "ope_test.py"

11

I don't think it's a problem of these test files.

13

test files are not touched in normal software use, they are only used by the software developers to verify that it works according to a narrow set of typical use before shipping to users. The domain name that you see are the one picked by developers as typical, they have no relation to production. That the test files are shipped with production software is only a by product of packaging limitations in fact. Don’t take them in account.
About your problem, maybe you could share nginx -T ? If you post the output on this forum, use the quoting magic of Discourse (the server software used on this forum), use three backticks ``` on a separate line to trigger text paste mode. Or post a link to a file.
