Description Luo Bin 2008-10-30 02:12:34 UTC
I can always receive a notify named "an internal system error has occurred" when packagekit tring to get update information.
My system is Fedora 10 rawhide on i686.
The PackageKit version: 0.3.9-2.fc10.i386
The error detail is below:

What's "rpm -qf /usr/lib/yum-plugins/rpm-warm-cache.py" ?

[xelnaga@ASUS6 ~]$ rpm -qf /usr/lib/yum-plugins/rpm-warm-cache.py

It's a problem with that plugin -- I can't find it in the fedora repositories, so I can't even reproduce. It also turned up no results on google. If you uninstall that plugin, does PackageKit work correctly?

Thanks very much!
This plugin actually caused the problem.
I removed it and PackageKit never report error again!
By the way,you can find the plugin here: http://koji.fedoraproject.org/koji/buildinfo?buildID=67993

Hi there,
This bug report is very old and based on a version not supported anymore. By upgrading to a newer version of PackageKit you could receive bug fixes and new functionality. You may need to upgrade your Linux distribution to obtain a newer version of PackageKit.
Please feel free to reopen this bug if the problem still occurs with the latest version.
