To prevent bad images to be spread through Over The Air updates (see thread "Don't update to RTM build") we have been forced to take down the image servers temporarily until we have a new images available.
Resulting from this ubuntu-device-flash will not function for any channels until the image servers are restored online. You are not able to flash any locally cached images either with the tool. [0] We will continue our efforts to get the new images available as soon as possible. If you phone has already downloaded a new OTA image in the background, DO NOT install the image. Sorry for the inconvenience. -- Antti [0] https://bugs.launchpad.net/ubuntu/+source/phablet-tools/+bug/1380079 -- Mailing list: https://launchpad.net/~ubuntu-phone Post to : ubuntu-phone@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-phone More help : https://help.launchpad.net/ListHelp
