Bug Description

Binary package hint: ubuntuone-client

While trying to add a folder to Ubuntu One using u1sdtool, I noticed that I kept getting these dbus errors... finally I tried

u1sdtool -q

and that failed to actually stop the syncdaemon.

So I killed off the syncdaemon manually and tried restarting but this is what happened:

bladernr@klaatu:~/development/checkbox/jobs$ u1sdtool --start

Oops, an error ocurred:
Traceback (most recent call last):
Failure: dbus.exceptions.DBusException: org.freedesktop.DBus.Error.NoReply: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.

The dbus timeout errors are the same ones I got previously when I tried to do ANYTHING with u1sdtool while syncdaemon was running. Unfortunately, I think the only way to get a working system again is to reboot, which not an optimal fix for whatever is causing this problem.

First, this is what happened when I tried subscribing a folder to be synced:

bladernr@klaatu:~/development/checkbox/jobs$ u1sdtool --subscribe-folder=/home/bladernr/Notes/

Oops, an error ocurred:

Then this:
bladernr@klaatu:~/development/checkbox/jobs$ u1sdtool -s

Oops, an error ocurred:

Then this:
bladernr@klaatu:~/development/checkbox/jobs$ u1sdtool -q
ubuntuone-syncdaemon stopped.

Though a ps axf showed that ubuntuone-syncdaemon was still running.

So I killed it using kill -9

then when I tried restarting, I got the error mentioned above at the beginning of this narrative.

Just rebooted to see if that helped. Immediately after reboot, this is what I get:

ubladernr@klaatu:~$ u1sdtool -s

So even after a fresh reboot I am unable to use u1sdtool to do anything... and since the "Sync with Ubuntu One" option has disappeared from the left click menu when in File Manager, I have NO way at all of adding new folders other than moving them into the Ubuntu One folder, which I really do not wish to do.

I can confirm this problem. Is there any workaround, or solution how to force ubuntu one to work again?

I can also confirm the issue. I'm running an Ubuntu 10.10 32bit Desktop Edition on my laptop as a virtual machine. (virtualcomputer.com)

Duane Hinnen (duanedesign) wrote :

Jeff,
This happens because of a less then optimal way metadata is handled in versions prior to what is now in nightlies and Natty Narwhal. Basically that's bug LP:436612. Anyone who has a fairly large number of files in their Ubuntu One directory I believe would want to try the nightlies PPA (please note that downgrade to older metadata storage is not possible).

If you are interested in testing the new improved metadata storage (which takes syncdaemon about a second or two to start) then please have a look at https://launchpad.net/~ubuntuone/+archive/nightlies. Please note that the nightlies releases are only automatically tested and there is a possibility that not all features are working at all times.

The commands to add the PPA:

sudo add-apt-repository ppa:ubuntuone/nightlies

sudo apt-get update; sudo apt-get upgrade

thank you,
duanedesign

I'd like to add, that this bug seems to also affect normal nautilus functionality. I discovered this issue after failing to run Nautilus normally. When I run the Ubuntu One client and try to check the 'Cloud Folders' and 'Devices' tabs, it shows me the same error in red. If I can get you any kind of logs, apart from the above mentioned stuff, I will gladly help.

I don't have many files in my Ubuntu One account and only two shared directories are specified.

This issue appeared suddenly without any explicit changes on my part.
