[Bug 1320306] Re: udm immediately sends a 'canceled' signal

Tue May 20 10:35:59 UTC 2014

Looking at the bug report:

'Credentials not found / Please log into your Ubuntu One account'

Ok, this is due to the fact that the click packages are now also updated
in the same system settings page. I think that gatox did update system-
setting to work correctly when you do not have a u1 account, if he has
not we should file a bug there. There reason for the u1 account beint
required is so that the system settings app can query the click store in
the server side.

Second, we are running this update in an emulator, that means that the
/tmp space is reduced and we might be hitting a state in which udm does
not have enough space to write the download in the file system. I
suspected, sorry, I strongly suspected, that it is the case due to the
udm logs stating:

E0516 18:31:41.610985  8073 file_download.cpp:659]  GroupDownload
{4f30e058b4dc4ed1a4104ff346179074 } Download ID{
e4a1dfa67427427399652316b13ef9cd } Could not write that in the file
system

Please ignore the previous error in the logs, it is due to the fact that
we cannot get the apparmor profile from the system image process, which
is due to the fact that system image runs uncofined.

Third, AFAIK system image will not be able to work in the emulator due
to the way the emulator works, we had a conversation with xnox about
this during the london sprint and unless he has changed anything in the
boot sequence of the emulator, even if the download is succesfull you
will not see the emulator upgraded.

Last but not least, I have assumed that udm could be wrong and I have
tested with the following code:

Go lang example using the go bindings I wrote for the mms client
(nuntium):

Python example:

http://paste.ubuntu.com/7492420/

The go example is using the sessiong bus while the python one uses the
system one. Both work as expected on the desktop and I have a strong
feeling that this is more related to the fact that the update is running
in the emulator that udm per se. I'll run a number of tests in a phone
to ensure that everything does work (for example, perform a system image
ipdate, click installations etc..). If everything works I would look at
another culprid ;-)

Bug description:
  I'm getting unhappy errors trying to upgrade a goldfish emulator
  instance using system-image.  If I try to update from the UI, I get a
  'Credentials not found / Please log into your Ubuntu One account'
  message that I've never seen before; if I try to do it from the
  commandline, I get the following:
