cobbler_web 在 CentOS 7.6 上不可用

當我嘗試載入 cobbler 2.8.4 網頁時，我在 /var/log/httpd/ssl_error_log 中看到以下錯誤

Traceback (most recent call last):

python2-django-1.11.20-1.el7.noarch

cobbler-2.8.4-4.el7.x86_64

cobbler-web-2.8.4-4.el7.noarch

看起來 Django 已經在 EPEL 中更新到 1.11，這對上下文處理器的處理方式進行了一些更改。程式碼 cobbler 試圖在這裡呼叫已被棄用並在不久前從 Django 中刪除，因此 cobbler 需要更新。在 Red Hat Bugzilla 中送出針對 cobbler 的錯誤報告。
