docker installation issue file not found after installation

Question

I installed docker on my ubuntu 14.04. deamon is running. but when I run

docker ps -a

I got this error -bash: /usr/local/bin/docker: No such file or directory

Answer 1

A quick fix can be adding a symbolic link (/usr/bin/docker -> /usr/local/bin/docker) :

ln -s /usr/bin/docker /usr/local/bin/docker

Answer 2

Maybe you are just lacking the permissions.

Try with

sudo docker ps -a

to see if it works.

If that is the case, proceed with the solution already indicated by @norbjd : create a simbolic link to point your docker commend to the root user docker executable.

ln -s /usr/bin/docker /usr/local/bin/docker
