Getting this error on 12.04 with the message:
org.freedesktop.DBus.Error.NoReply: Message did not receive a reply (timeout by message bus)

[Silviu C. (silviucc)]

Happens on 12.04 64bit alpha 1.

[Till Ulen (tillulen)]

Same crash on 12.04 alpha 1 (i386) when trying to install the Google Chrome .deb file downloaded from http://www.google.com/chrome.

[Christopher Kyle Horton (christhehorton)]

I am able to open the Software Center just fine, but I cannot install/remove anything in it. This is described in bug 897984 which was marked as a duplicate of this one, although I did not see any associated error messages or Apport windows.

[C de-Avillez (hggdh2)]

Marking Triaged/Critical. This obviously affects many users, and makes software installation for the casual user impossible,

[crtm (carlosrtm)]

Same for me to (Affected 12.04, kernel 3.2.0-1) afeter update kernel today

[Christopher Kyle Horton (christhehorton)]

Ran a partial upgrade today and I'm still seeing this with software-center 5.1.3.1. This time I did get an Apport window, which led me to duplicate bug 849553.

[Simba MacDhuibh (spacesimba08)]

You can still apt-get it at least.
12.04 AMD64 here.

[Harry Hall (vickyharryhall)]

this will probably be fixed in the final release

[Christopher Kyle Horton (christhehorton)]

@Harry: Probably, but hopefully it gets fixed much sooner than that, especially since it is marked as Critical.

[cyrpaut (cyrpaut)]

Same bug on ubuntu 10.10 amd64, software-center 5.0.3.1.

This appens after some manual package installation (I suspect dropbox or mendeley)

The application list is also broken on unity, and apps cannot be found not search on the pannel. Persist after reconstruction of the application index, using apt-get update and upgrade, nor apt-get -f install, nor sudo apt-get install 4g8 && sudo dpkg --force-depends -r libnet1 as found here https://wiki.ubuntu.com/SoftwareCenter#broken-catalog

The bug appeared on a brand new installation of ubuntu (2days, just installing my progs)

Here is attached the report of the software-center --debug please note that I used no proxy and disabled third party packages sources and apt-get update. After these lines, the terminal is freezed

Please note that, once the command is launched, there is no way of killing it in the terminal by ctrl-C and the process is not visible in "top".

Hope it can be useful

[cyrpaut (cyrpaut)]

By looking at the different reports available in the different bugs, i notice that the backgound of the bug and the modules implicated are way different. In mine, it start with a proxy ploblem, and some other it's a database that is corrupted.

There may be different bugs that makes the software-center to loose itself. It's possible to produce the bug by intalling an external packet. Some people report skype package, but for me it's others.

Can one that know the arcanes of the app center fix that? It appears to be really critical. On the top of that the system is not usable easily anymore, since the app list in the panel does not display apps anymore.

[Rigved Rakshit (rigved)]

I get this even with the latest updates. But the Software Center window does not close and I can use the Software Center just fine. But the error keeps popping up still.

[Brian Smith (brian-smith-i)]

Still doesn't work, and there are problems with update manager too

[Rigved Rakshit (rigved)]

Sorry, I take my earlier comment back. It seemed that the Software Center was working fine. But no, I can only search applications and view their info, screenshots etc. But when I click on Install button, nothing happens.

[Jean-Baptiste Lallement (jibel)]

I got it with on software-center launch after having reproduced bug 907568 and launched S-C again.

[Doug McMahon (mc3man)]

At least here on a 12/31 image the upgrades today to *aptdaemon* - 0.43+bzr756-0ubuntu1/ *dbus * - 1.4.16-1ubuntu2, ect. have seemingly fixed S-C

It now opens fairly quickly, & more importantly installs/removes packages with no issues or hangs. Tried multiple times.

[Gary Lasker (gary-lasker)]

Hello Doug, thanks for your note! Indeed, this one appears to be fixed in today's aptdaemon update in Precise. Many thanks to Chris Coulson for the fix!

aptdaemon (0.43+bzr756-0ubuntu1) precise; urgency=low

[jeff E (thenessus)]

ok, if this is fixed, how can people who have this problem - who do not want to re-install the entire machine - can solve this?

[Justin (parksjw)]

Has this patch been applied in Oneiric proposed already? I have:
Package: software-center 5.0.4
and it seems to still be affecting me.

[Sebastian Heinlein (glatzor)]

Oneiric is not affected by this bug or you have got a different one. just update your machine.
