unable to run certbot --nginx - UnicodeDecodeError: 'ascii' #5236
Description
My operating system is (include version):
ArchLinux (Kernel 4.13.11-1)
I installed Certbot with (certbot-auto, OS package manager, pip, etc):
pacman -S cerbot-nginx
I ran this command and it produced this output:
cerbot --nginx
Certbot's behavior differed from what I expected because:
Saving debug log to /var/log/letsencrypt/letsencrypt.log
An unexpected error occurred:
UnicodeDecodeError: 'ascii' codec can't decode byte 0xe2 in position 330: ordinal not in range(128)
Please see the logfiles in /var/log/letsencrypt for more details.
Here is a Certbot log showing the issue (if available):
