Unable to sync between computers

[Alberto Salvia Novella]

*********************
STEPS TO REPRODUCE
*********************
1. Initialize session in two different computers which are synced using Ubuntu One.
2. In the Software Center of one of these computers, enable the "sync between computers" option. This can be done by the Software Center's "file" menu.
3. Do the same in the Software Center of the second computer.

*********************
EXPECTED BEHAVIOUR
*********************
The Software Center of the second computer to show the first computer to be available to sync.

****************
REAL BEHAVIOUR
****************
The Software Center never shows a different computer than the local one.

****************

Status changed to 'Confirmed' because the bug affects multiple users.

[Brian Millan (brian.millan)]

What other info can I supply?

Ubuntu 13.04
software-center 5.6.0-0ubuntu2
uname -a Linux 3.8.0-21-generic #32-Ubuntu SMP Tue May 14 22:16:46 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux
terminal output attached

FWIW this is reproducible on all three machines I have:

ASUS A53Z AMD A6-3420M 1.5 GHz AMD Graphics
GIGABYTE GA-D525TUD Intel Atom D525 1.8GHz Intel Graphics
ZOTAC IONITX-L-E Intel Atom 330 (1.6GHz, dual-core) NVIDIA Graphics

x86_64 on all three.

[Alberto Salvia Novella (es20490446e)]

Are the three machines running Ubuntu 13.04?

[Brian Millan (brian.millan)]

@Alberto

Yes all running 13.04.
Have also tried:

oneconf-query --list --hosts

The result is only the host that I run the command on is listed. Haven't tried:

oneconf-query --debug --list --hosts

yet.

I think this bug report is now rich in detail and ready to be worked on.

SETTING IMPORTANCE TO HIGH

Since this flaw triggers bug #1197568, rendering essential features or functionality of the application or dependencies broken or ineffective, it has an importance of "high".

[John Russell (jrussell-88)]

I have the same problem with a fresh install of Ubuntu 13.04 x64.

Software Centre says on the bottom of the Sync Between Computers page: 'To sync with another computer, chhoose "Sync between Computers" from that computer.' No other computers are listed.

The UbuntuOne app - Devices tab - lists all my pcs under my account, and files are syncing across all the machines.

From my Ubuntu One account on the web - My Account - Devices - I can see that the other machines - Ubuntu 11.04 to 12.10 - have logged in to sync but Ubuntu Software Centre on the 13.04 machine hasn't yet linked to Ubuntu One.

[Alberto Salvia Novella (es20490446e)]

This renders paid applications not to be installable in multiple devices.

[Alberto Salvia Novella (es20490446e)]

Since this bug severely affects applications beyond the package responsible for the root cause, it has an importance of Critical.

[Alberto Salvia Novella (es20490446e)]

Please, confirm bug #1197568.

Thank you.

Have 3 computers, all 13.04 amd64 and no other is listed on every single computer. They are perfectly isolated in software center, but work together in ubuntuone.

Here is the missing test from above:

[Hermann (blablup-b)]

Same problem here:
I have 2 computers, both 13.04 amd64.
After choosing sync, software center shows only the local pc but never the other machine.
Ubuntu1 shows both machines; file sync works fine.

[Hermann (blablup-b)]

Attached is the console output after starting softare-center.

[VladimirCZ (vlabla)]

Same problem here with 13.04 amd64.
After choosing sync, software center shows only the local pc but never the other machines that have 12.04 amd64 and can see each other without problem.

[Kevin C. (kedoc)]

I got exactly the same behavior on my personal (i386) and professional (amd64) computers, both running Ubuntu 13.04 and connected on the same Ubuntu One account.

If it can help, here is what I get when I start oneconf-service in debug mode (the log shown here is from Ubuntu 13.04 i386):

I think that this issue is linked to/caused by this one: https://bugs.launchpad.net/ubuntu/+source/oneconf/+bug/1165104

[Alberto Salvia Novella (es20490446e)]

Status changed to 'Triaged' because the bug is:

- Valid.
- Well described.
- Reported in the upstream project.
- Ready to be worked on by a developer.

[Mike Cole (mikecole)]

I see this has been sitting here for 2 months with no additional updates noted. Is there any movement expected on this issue for 13.04? I tried updating to 13.10, but it broke my openconnect which is absolutely vital to me doing my job, so I was forced to roll it back. I never got so far as to try the software sync in 13.10. Can anyone comment on the odds of actually getting a fix for this in 13.04 before support ends? I really don't want to have to wait until April's LTS release to get a functional sync in place if I don't have to.

[Alberto Salvia Novella (es20490446e)]

Since this bug:

- Impacts the ease of use.
- Is easy to fix.
- Would be encountered by the average user.
- Affects the default installation of the latest Ubuntu or Kubuntu desktop release.

it's a paper cut.

[Alberto Salvia Novella (es20490446e)]

Since this bug has a severe usability impact on a small portion of Ubuntu users, it has a priority of "High" on the "One Hundred Papercuts" project.

[Alberto Salvia Novella (es20490446e)]

Since this bug:

- Has a status of "Triaged" in Ubuntu.
- Its fix is already evident.

it's also triaged in the "One Hundred Papercuts" project.

[Bruno Nova (brunonova)]

As already mentioned, the problem is probably in oneconf: Bug #1165104.
I've added a patch to that bug that can, luckily, help to fix it. A developer should check/test it.
