update-manager crashed with DBusException in commit()

ror message and can result from a lot of different things. It'd be useful if you were to review and add AptDaemon messages from your syslog when this occured to this bug report. You could get this information using the following command:

grep AptDaemon /var/log/syslog

Thanks in advance.

Seems to happen to me every time I run the update-manager after installing 12.04

I was redirected to this page by my sistem, as it said a bug was reported.

After updating there are still updates visible in the update manager, on install it crashed.
The updates show up but have no boxes ticked. Had a lot of trouble with the update manager.
Had a lot of partial upgrade warnings so unsure if its the previous updates that play a part in this.

(Similar observations as feedback from jeroen Tiel (js-t) in previous bug report)
While using Update Manager, updates still showing as visible but not checked and "greyed out" like they're disabled. Crash reported, and upon relaunching Update Manager it appears all updates completed properly.
(I'd been getting a lot of "partial upgrade warnings" and "can't get lock" like Aptitude, Synaptic has a lock but I'm not aware of any other package management systems running.)

Happened while I was updating the list of upgrade packages. I initially had 149.5 GB but that was from yesterday when I checked. Decided to wait a day and did a recheck for updates. During this "update" the error happened. Hope this helps. Now I have a "System program problem detected" showing on the screen. Hope this helps.

As in #7. The unchecked boxes updates slowly disappeared one at a time over a period of 10 minutes.

I have installed ubuntu 12.04 beta 2, the system did not update during the process of installation of Ubuntu, appeared 502 available updates in the update manager afterwards to initiate the system, select the opcion to install updates and begins the download, however, does not show the window "applying changes", neither asked me the password of user, the error occurs some minutes afterwards. Finally I open again the update manager, this time works with normality.

From a duplicate in precise we have the following traceback:

Traceback (most recent call last):

DBusException: org.freedesktop.DBus.Error.UnknownMethod: Method "Set" with signature "sss" on interface "org.freedesktop.DBus.Properties" doesn't exist

This is still an issue as indicated at errors.ubuntu.com and it is occuring with the latest package version, 0.156.14.7, of update-manager in precise.

Got this bug as I locked the screen with light-locker, logged into the Guest account (so my main account should still be running), then logged out of the Guest account and logged back into my main account.
