我从Ambari 2.7.2启用了Kerberos，并从Kafka和HBase测试了身份验证。现在，我尝试安装Apache Ranger进行授权。在Unix中使用Mysql DB。已安装Ranger admin，但未安装Ranger用户同步。我在Ambari UI中遇到错误。
RuntimeError: Failed to execute command '/usr/bin/apt-get -o Dpkg::Options::=--force-confdef --allow-unauthenticated --assume-yes install ranger-3-1-0-0-78-admin', exited with code '100', message: 'E: Failed to fetch http://public-repo-1.hortonworks.com/HDP/ubuntu16/3.x/updates/3.1.0.0/pool/main/r/ranger/ranger-3-1-0-0-78-admin_1.2.0.3.1.0.0-78_all.deb 403 Forbidden
E：无法获取某些档案，可能运行apt-get update或尝试--fix-missing吗？
在Ambari审核日志中，我遇到了以下错误
