Thanks for your bugreport.

This should be fixed with the latest python-dbus package. Could you please install it and see if that fixes the issue?

Thanks,

I have spoken too early, this bug is not related to the python-dbus problem (a speperate bug).

Added a python2.5 task as it seems like python2.4 generated pickle files can't be read by python2.5 anymore.

Ok, I can reproduce the problem here just fine with the following command:

$ sudo python2.4 /usr/sbin/update-app-install ; gnome-app-install
and it crashes reliable

$ sudo python2.5 /usr/sbin/update-app-install ; gnome-app-install
and it works fine.

The code builds a medium complex pickle.

Please note that this is a different bug than #74773. This one is a pickle problem, the other one is a python-dbus error.

more or less same experience for me. I installed Feisty in a virtual machine under vmware server 1.0.1, ran updates successfully, then attempted add/remove for other programs. it crashes after a few seconds, just long enough to show splash screen...

file attached below

Ok. I think I'm fixed. I ran:

$ sudo python2.5 /usr/sbin/update-app-install ; gnome-app-install

and it works fine.

I'm posting on the python-dbus bug error page. I'm new to this so sorry for my confusion.

I had the same problem. I don't know if this happenede because I upgraded to a dev version of ubuntu and if this problem would not occur for updates to the release version of feisty.
Nevertheless, if the pickle-file is corrupt for whatever reason, it would be nice if gnome-app-install would recover from that error. The attached patch should do the job.

add remove also wont open for me on feisty. i'm on amd64 and here's my crash report attached

Same here

Same here,

I have a fresh install of feisty herd 2 (downloaded 30min. ago) and also "add/remove ..." didn't work.

Same mistake

when I run

$ sudo python2.5 /usr/sbin/update-app-install ; gnome-app-install

I get the following messageCaching application data...
Generating mime/codec maps...
Traceback (most recent call last):
  File "/usr/bin/gnome-app-install", line 208, in <module>

    from UpdateManager.Common.aptsources import SourcesList, is_mirror
ImportError: No module named UpdateManager.Common.aptsources

Problem solved with last update (version 0.3.6).

I guess we can close this one, right, Michael?

Unfortunately, I failed to backup the "menu.p" pickle file that triggered this bug so I can't tell if the new release fixed the bug. Forcing update-app-install as root seems to recreate the menu.p file so that it works again, so maybe the actual bug was that this has not been forced after transition from edgy to feisty.

Nevertheless, if the menu.p is corrupt for some reason, gnome-app-install does not handle it and crashes. This is never good. See my patch above for a fix.

Hi,

Just a quick note: the lastest update to gnome-app-install version 0.3.6 fixed the problem.

$ sudo apt-get install gnome-app-install

Denis, Jonh just said that two comments ago, and the status is Fix Released. Also, I think it is safe to assume that people here know how to use apt.

As for the patch, I agree with Christof here - even if the problem isn't occurring any more, the patch should still be applied, since it would prevent a whole class of possible bugs where the pickle file was corrupted.

Is there some reason for not applying the patch, besides the obvious reason that it would be a change to the code?

No, there's no reason for not applying the patch, IMHO it's clear and
safe enough to me (without being a developer/packager of that
package).

Regards,

Denis

I might add that I applied the patch as well. Its nice and simple and protects against other potential problems too. Thanks for it!

This bug has been declared as fixed, however I did not manage to see any improvement when testing all this week's (up to Jan 26) builds of amd64 desktop, which has built-in gnome-app-install version 0.3.6

Might be a particularity of amd64 and/or my testing in vmware.

caused by the new python-dbus package

Hi MLucius,
the crash caused by dbus is not related to the original bug reported here.

The dbus-python-problem has been reported in bug #81727 and bug #81835

Crash also happens with 20070129 & 30 amd64 desktop live (in vmware) for a bit different reason, see attached log.

http://sourceforge.net/tracker/index.php?func=detail&aid=1675967&group_id=5470&atid=105470 upstream bug

fixed in python2.5.1 in feisty

Installer keeps crashing. will not let me install third party hardware drivers. will not let me install Nvidia X-org
