Bug Description

Just updated mako to #63 from some previous release (not entire sure what)
It downloaded the update and then when I hit the "Install & Restart" button I got this message:-

"Apply update failed: Can't apply the current update (can't contact service)"

But I couldn't take a screenshot because it immediately rebooted and started updating. Seems to have updated okay, but was alarmed to see this message.

From the frontend code, it means that ApplyUpdate() backend call doesn't send an answer anymore to the frontend with an empty string telling "ack".

TL;DR you can ignore the error message - the device will still update just fine after a reboot.

In order to fix Bug #1217098, I made a change to the ApplyUpdate() D-Bus method, as described in Bug #1247215. This was communicated through the ubuntu-phone mailing list, but no human or automated check was in place to make sure system-settings was prepared for the change. That's a subject for a different discussion.

All it means though is that system-settings is not getting its expected empty return string after calling ApplyUpdate(), but in the predominately most common case, the device will successfully reboot and apply the changes, so any return value is mostly useless anyway (except for the user confusing error message). So, no functionality is broken, but we unfortunately do show this confusing message.

I'm closing the upstream bug task, since bug #1260768 will track the proper long term fix.
