I was installing Docker on Ubuntu (14.04.1 LTS)\u00a0in my home lab for the first time following the instructions at\u00a0http:\/\/docs.docker.com\/installation\/ubuntulinux\/<\/a> this evening and came across an issue.<\/p>\n

Docker would not start and was showing the following error:<\/p>\n

Cannot connect to the Docker daemon. Is 'docker -d' running on this host?<\/pre>\n

Checking processes I don’t see docker running:<\/p>\n
$ ps -ef | grep docker<\/pre>\n
alex\u00a0 \u00a0 \u00a0 3703\u00a0 2113\u00a0 0 21:27 pts\/0\u00a0 \u00a0 00:00:00 grep --color=auto docker<\/span><\/pre>\n

Trying to start docker generated the following errors in \/var\/log\/syslog<\/em>:<\/p>\n
kernel: [\u00a0 608.236848] init: docker main process ended, respawning<\/pre>\n
kernel: [\u00a0 608.451873] init: docker main process (4230) terminated with status 1<\/pre>\n

kernel: [\u00a0 608.676445] init: docker respawning too fast, stopped<\/pre>\n

After trying a bunch of different fixes which didn’t work, then looked up the docker log at \/var\/log\/upstart\/docker.log<\/em>, which displayed the following:<\/p>\n
Error loading docker apparmor profile: fork\/exec\/sbin\/apparmor_parser: no such file or directory ()<\/pre>\n

A quick install of apparmor fixed this!<\/p>\n
$ sudo apt-get install apparmor<\/span><\/pre>\n

And now…<\/p>\n
$ ps -ef | grep docker<\/pre>\n
