I am trying to install ambari on ubuntu 16.04 LTS on server with zero internet access. I am following the steps mentioned in: https://docs.cloudera.com/HDPDocuments/Ambari-2.7.4.0/bk_ambari-installation/content/ I hosted a local repository using apache http server. I configured to use local repository in /etc/apt/sources.list.d/ambari.list. The file contains #VERSION_NUMBER=2.7.4.0-118 #json.url = http://public-repo-1.hortonworks.com/HDP/hdp_urlinfo.json deb [trusted=yes] http://my.repository/ambari/ubuntu16/2.7.4.0-118/ Ambari main   when I run sudo apt-get update it is not fetching the binaries. I am attaching log of the process Get:1 http://my.repository/ambari/ubuntu16/2.7.4.0-118 Ambari InRelease [7379 B] Ign:1 http://my.repository/ambari/ubuntu16/2.7.4.0-118 Ambari InRelease Get:2 http://my.repository/ambari/ubuntu16/2.7.4.0-118 Ambari/main amd64 Packages [1513 B] 0% [Connecting to archive.ubuntu.com (91.189.88.31)] [Connecting to security.ubuntu.com (91.189.88.173)] As there is no internet access it fails after this. Is there any configuration I am missing for offline installation. Any help is appreciated. Thanks!!   ... View more
