[Resolved] Ubuntu Touch updates are currently interrupted
-
Edit: The situation is now resolved.
Hello everyone,
I regret to inform you that we made an oversight and allowed the Image Signing key for https://system-image.ubports.com expire. We are working to remedy the issue, but in the mean time downloading updates to Ubuntu Touch is not possible. You will receive a "FileNotFoundError" referencing a keyring file upon trying to update.
Only the on-device image updater is affected. Installing Ubuntu Touch using the UBports Installer is still possible. You may still update apps and use your Ubuntu Touch device normally. Since there has not been a recent stable update, most users are not highly impacted by this issue.
To ensure that this never happens again, we are implementing automatic checking of the image signing keys: https://github.com/ubports/build-scripts/pull/10
This post will be updated as new information becomes available. You may also track this issue at https://github.com/ubports/ubuntu-touch/issues/1120

It appears that the situation is resolved for any new installs of Ubuntu Touch or installs which did not attempt to update during the time that the key was expired. Those who tried to update while the key was expired are still receiving the FileNotFoundError. We are continuing to investigate.

The issue is now resolved. All of the current candidate images have now been re-signed and should work properly.
