环境

Ubuntu 22.04 LTS
Bugzilla 5.0

解决

官方两篇文章部署目录不一致，官方部署文档采用新建 /var/www/webapps 目录，而关联文档中 apaache 采用 apache 默认目录 /var/www/html。

mv /var/www/webapps/bugzilla /var/www/html/
systemctl restart apache2

重新运行 testserver.pl 测试命令即可。正确提示：

TEST-OK Webserver is running under group id in $webservergroup.
TEST-OK Got padlock picture.
