These containers depend on 'sudo' being installed, which up until 14.04.4 the latest image had.\r\n\r\nWhen 16.04 became the latest, my containers broke. While I understand I can modify my containers to use 14.04 specifically or install sudo, it seems this change might cause problems for others, so I thought I'd report it.\r\n\r\n% docker run ubuntu:14.04.4 sudo echo foo\r\nfoo\r\n\r\n% docker run ubuntu:16.04 sudo echo foo\r\ndocker: Error response from daemon: Container command 'sudo' not found or does not exist..\r\n"}}
