问题
I had an app running on another bluemix account. I wanted to copy the app and run it in another bluemix account. So I downloaded code from github repo., but when I am trying to push this app to another account I am seeing following error.
Note : I used cf push to push the downloaded app. Any help ?

Please check your Manifest.yml. Either your app is missing it or has some wrong entry. you can look for this file in your downloaded app. And also don't forget to pass build pack name when running push command.

What language is the app in? Sometimes Cloud Foundry can't detect the type of app you are running and when you push the app you need to tell it what kind of app it is. We can do that with some of the following commands. I went ahead and posted it for a couple different languages. More info here. https://www.ng.bluemix.net/docs/#starters/byob.html
To see all the "built in" buildpacks run the following command.
cf buildpacks
You will get something like the following.

Java App:
cf push appname -b liberty-for-java
or cf push appname -b java_buildpack
Node.js:
cf push appname -b sdk-for-nodejs
or cf push appname -b nodejs_buildpack
Ruby:
cf push appname -b ruby_buildpack
There are a bunch of other languages supported as well.
For a list head over to https://github.com/cloudfoundry-community/cf-docs-contrib/wiki/Buildpacks.
If for example you wanted to use PHP you would do the following.
cf push -b https://github.com/cloudfoundry/php-buildpack.git
If you wanted to do Go you would do the following.
cf push appname -b https://github.com/cloudfoundry/go-buildpack.git

two ways to sort out this issue(Assuming its a node.js app)
Run command like below from cf tool mentioning app name :
cf push testmyapp -b sdk-for-nodejs -n testmyapp -m 128M -c 'node main.js'
P.S- "-n" option is used for required hostname on bluemix
mention app name,service name explicitly in manifest.yml file like below:
applications:
- name: testmyapp
host: testmyapp
memory: 128M
command: node main.js
P.S- You need to create manifest.yml explicitly if you are using 2nd method.
If you still getting any error,please provide o/p of "cf logs testmyapp --recent"
Alternatively,you can even directly push your app like below:
For Go application to Bluemix, but need to supply -b with the Go Buildpack URL:
cf push appname -b https://github.com/cloudfoundry/go-buildpack.git
Similarly,you can do for other one's.

Looking at the below error,your app is not able to detect correct type of SDK.
2014-12-16T14:49:48.62+0530 [STG] OUT Staging failed: An application could not be detected by any available buildpack 2014-12-16T14:49:49.37+0530 [API] ERR Encountered error: An app was not succ essfully detected by any available buildpack
you need to check the correct sdk type and mention it while pushing like below:
cf push myapp -b sdk-for-nodejs -n myapp -m 128M -c 'node main.js'

I had a talk in the last CloudFoundry summit on all kinds of app push errors: their symptoms, how to diagnose and what are the solutions. See https://www.slideshare.net/greensight/10-common-errors-when-pushing-apps-to-cloud-foundry. Hopefully it will be helpful.
