mup deploy failing

[chouhanv]

I am using mup version 0.11.2 since long time and never having any issue updating my meteor app.

But suddenly it start giving me error when i am trying to upload new version of my app. I am getting following error -

mup deploy

Meteor Up: Production Quality Meteor Deployments

Building Started: .
=> Build Error. Check the logs printed above.

But when i am trying to check the log using mup logs -f it says
tail: cannot open `/var/log/upstart/allsaid.log' for reading[server ip] : No such file or directory

So i am not getting what is the actual error which is causing the deployment fail.

Here is the OS and version i am having on machine using for deploy
uname -a
Linux x86_64 x86_64 x86_64 GNU/Linux

Node - 0.10.38
NPM - 1.4.28
Meteor - 1.1.0.3

I have tried mupx too but it is also getting stuck on mup setup command.
mupx logs -f shows "docker command not found"

Can anyone help me out to fix this issue?
