apt_check.py crashed with SIGSEGV in pkgCacheGenerator::MergeList()

Also I have this problem with Linux monkey-desktop 2.6.31-12-generic #40-Ubuntu SMP Wed Oct 7 04:14:43 UTC 2009 i686 GNU/Linux

I´m using Ubuntu Karmic Koala 9.10 Beta

I was just installing skype when the program synaptic crasht on the installation off skype.
Ubunto Karmic Koala 9.10 beta oktober

Since updating to karmic with dist upgrade I have seen this a few times, just received it again now after performing :
sudo update-apt-xapian-index
Due to not seeing updates in Synaptic correctly.

Clean installed netbook has no problems,

Also experienced in Lucid (see Bug 510788) whilst running wajig dist-upgrade.

Bug 509990 which is a duplicate of this contains a stacktrace.

I've just been directed here from a crash in Lucid whilst trying to set up a mobile broadband dongle using Betavine's VMC.

While updating this error came true the updating process in Lucid.

Nearly every time i update lucid with synaptic this error occured.

I just clicked on the "Search" button on Synaptic and then this error appeared.

I got this problem in lucid, just after removing some packages from my system in synaptic. This was version 0.99.1 of update-notifier-common.

Just did a clean install of Lucid 2010-04-02 on a Dell Mini 9. Installed a few packages with the GUI tool in the Applications menu, then a few more using apt-get. Then added the file /etc/apt/apt.conf/99proxy to use apt-cacher available on one of the boxes on the local network:

    Acquire::http::Proxy "http://192.168.0.3:3142/apt-cacher/";

After that, did a "sudo apt-get update", and moments after it had finished, got the "apt_check.py crashed" error window.

Upgrading status to Triaged, Medium. There should be more than enough debugging information from the log files contained in the duplicates here for a developer to take a good look at this. Thank you all for reporting this to us, and please continue to report any other bugs/problems you may find.

[UBUNTU 10.4 Beta 2+updates] mail-notifier cannot access keyring to store password. Keyring-daemon seems to be absent.

I came the upgrade path Ubuntu 9.10 -> 10.04beta

I faced this issue while I was manually uninstalling some packages using synaptic.
I have the feeling that the automatic upgrade checker kicked in after I uninstalled a first bunch of packages, just before I uninstalled additional packages.
Did apt_check.py choke on an APT lock file?

happened on 10.04 LTS (final) in a normal automatic packages update

@efa, did you install packages from repositories (e.g. proposed) that you later disabled, leaving the packages "obsolete"? I was in this situation and started seeing this problem after a recent update. Then I downgraded the packages back to what the enabled repositories provided and the problem went away.

as I remember I only installed "final" packages from packages manager.
Out of them, Seamonkey 2 and OpenOffice 3.2 was installed with provided builtin installer on the old Ubuntu 9.10.
I also cleaned the installed packages with:
# apt-get autoremove
before and after the distribution upgrade.

Closing due to age. No activity since 10.04.

If a similar bug appears in Ubuntu 14.04 please open a new report.
