Trouble deploying app from Ubuntu SDK to phone

Question

I'm trying to run the App with Simple UI template on Nexus 4 but I'm getting these warnings

Under Issues

warning: desktop_Exec (app): found unexpected Exec with architecture 'all': ./qtc_device_debughelper.py
warning: security_policy_groups_safe_app (debug): (REJECT) reserved policy group 'debug': not for production use
The debug policy group is automatically injected and should only be used for development. To create a package for the store use the publish tab!

Under Application Output

Sdk-Launcher> Installing the application failed
Warning: Permanently added '[127.0.0.1]:10000' (RSA) to the list of known hosts.
Sdk-Launcher> Executing:     /tmp/com.ubuntu.developer.username.helloworldtest_0.1_all.click

I have trusty proposed installed on the Nexus 4 and I created an armhf 14.04 kit. The SDK does seem to detect the device properly from under options,devices.

I've had this working before, I'm not sure what is wrong now. I just reinstalled everything but nothing changed/helped.

EDIT:

Just put 14.10 on Nexus 4 and made a 14.10 kit. The helloworld app ran without any problems, could this be a 14.04 specific issue?

First ensure the USB Cable is working correctly and try to connect it directly without a USB HUB.

Then on Ubuntu Touch go to Settings → About this phone. Then go all the way to the bottom Developer Mode, set a Lock security to your liking and then turn on Developer Mode
