In an issue similar to bug #723323, I get an "sqlite3.OperationalError: database is locked" error with Anaconda in Fedora 16 Alpha. The difference is that I'm seeing this error during a postinstall script rather than in the installer itself.

The following two lines are in the kickstart script in a postinstall script:

rpm -Uvh http://linuxdownload.adobe.com/adobe-release/adobe-release-i386-1.0-1.noarch.rpm
yum -y install flash-plugin

The corresponding output is:

"""
