Automated screen unlock not working on wily images

[Francis Ginther]

The method to automatically unlock the screen prior to running autopilot tests is not working on wily images. For example:

https://jenkins.qa.ubuntu.com/job/generic-deb-autopilot-runner-wily-mako/417/console

The CI automation uses this script to setup and perform the unlock:
http://bazaar.launchpad.net/~ubuntu-test-case-dev/ubuntu-test-cases/touch/view/head:/utils/host/reboot-and-unlock.sh

The failure is seen on images from "ubuntu-touch/devel-proposed/ubuntu", in this case image 276.

Attached is the full console log from that run.

[The relavent messages are:]
I: Unlock attempt 1 failed, script output: 'initctl: unable to determine sessions
initctl: unable to determine sessions
Error connecting: Cannot autolaunch D-Bus without X11 $DISPLAY
'
I: Unlock attempt 2 failed, script output: 'initctl: unable to determine sessions

I: Too many unlock failures, giving up

The above log suggests it's not the tool that's failing, but rather the shell environment isn't complete - i.e. dbus and upstart details are not available.

I just tried following http://ubuntu-test-cases-touch.readthedocs.org/en/latest/ on mako with devel-proposed:

I just noticed:

The job seems hardcoded on image 276 for some reason, when we're at 311 already, and that's what I've tested. Trying with image 276 now.

[Francis Ginther (fginther)]

The jenkins job was indeed hardcoded to use image 276 due to an unbootable image at 277. We then failed to remove this once the image was fixed. Image 311 is working and unlock is successful:

https://jenkins.qa.ubuntu.com/job/generic-deb-autopilot-runner-wily-mako/421/consoleFull

[log snippet]
INFO:reboot-and-wait:Network is active
I: Unlock attempt 1 failed, script output: 'Error: GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name com.canonical.UnityGreeter was not provided by any .service files
'
I: Unlock passed

This is now working (transient failed attempts are expected). I think we can close this.
