Hello,

two weeks ago I used certbot and haveing no troubles.
Now I’m getting the following when trying to request certificate once again:

certbot -d christian-burgert.de -d *.christian-burgert.de --manual --preferred-challenges dns certonly

UnicodeDecodeError: ‘ascii’ codec can’t decode byte 0x82 in position 1: ordinal not in range(128)
Please see the logfiles in /var/log/letsencrypt for more details.

Any idea?

The stack trace, to me, appears to be failing on a file name.

sudo find /etc/letsencrypt/{archive,live,renewal} -type f,l

Edit: on second thought, it’s probably the file contents, which might be a bit tricky. If you can add a

print(target)

immediately before:

 return crypto_util.get_names_from_cert(f.read())

in /usr/lib/python3/dist-packages/certbot/storage.py, it might reveal what the cause is.

Cool thanks!

Find a corrupt text in a cert.

Now it works fine. Thanks!
