produced an unexpected error: ‘ascii’ codec can’t decode byte 0xe9 in position

把配置文件里的中文字符串删除就好了

  1. $ sudo grep -r -P ‘[^\x00-\x7f]’ /etc/apache2 /etc/letsencrypt /etc/nginx
  2. 將看到的內容，全部進去檔案刪除
  3. 刪除這些編碼後，在重新執行 Let’s encrypt script 就可以通過囉~
Attempting to renew cert (www.xxx.com) from /etc/letsencrypt/renewal/www.xxx.com.conf produced an unexpected error: 'ascii' codec can't decode byte 0xe9 in position 5: ordinal not in range(128). Skipping.
All renewal attempts failed. The following certs could not be renewed:
  /etc/letsencrypt/live/m.xxx.com/fullchain.pem (failure)
  /etc/letsencrypt/live/www.xxx.com/fullchain.pem (failure)
