[Bug 1260712] Re: Apply update failed: Can't apply the current update (can't contact service)"

[Barry Warsaw]

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.

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

Status in Ubuntu system image (server/client/updater):

Status in “system-image” package in Ubuntu:
  Fix Released

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.
