[Alan Pope 🍺🐧🐱 🦄]

It is indeed critical issue. We have two options:

1. get the openssh-server installed by default on the image so the development mode enabling would need to exchange the autehtication keys

2. touch the /userdata/.writable_image file on the RO system, reboot, install the openssh-server, remove the /userdata/.writable_image file and reboot

[Pat McGowan (pat-mcgowan)]

The plan is to add SSH to the image, it will not start by default and it will need a special config and the USB driver needs to be properly set up

We are planning to publish an HTML5 tutorial on dev.u.com week of Sept 16. The tutorial is planned to include running the app on the device, which is now broken. So please specify a simple workaround or fix this quickly please or the tutorial will need to drop running the app on the device.

One workaround is flash with cdimage-touch. I am not certain whether this path is ruled out for the public sdk tutorial due to status of cdimage-touch path.

lxc-android-config (0.95) saucy; urgency=low

  * make /etc/init/ssh.override a rw file so something like:
    echo "" | sudo tee /etc/init/ssh.override can be used to enable the ssh
    service permanently if needed.
    echo "manual" | sudo tee /etc/init/ssh.override can be used to disable it
    again

please modify the openssh_install script to (and probably just call it openssh_enable now) to us the above way to enable ssh
