I think I have the same problem. In my case install of the flashplugin- installer 11.2.202.228ubuntu3 locks up in the following processes:
root 8599 8598 0 08:53 pts/1 00:00:00 apt-get install flashplugin-installer root 8618 8599 0 08:53 pts/2 00:00:00 /usr/bin/dpkg --status-fd 47 --unpack --auto-deconfigure /var/cache/apt/archives/flashplugin-installer_11.2.202.228ubuntu3_i386.deb root 8628 8618 0 08:53 pts/2 00:00:00 /bin/sh /var/lib/dpkg/info/update-notifier-common.postinst triggered /usr/share/package-data-downloads root 8629 8628 0 08:53 pts/2 00:00:00 /usr/bin/python /usr/lib/update-notifier/package-data-downloader If I kill the last process, the installation then completes as follows: The following NEW packages will be installed flashplugin-installer 0 upgraded, 1 newly installed, 0 to remove and 0 not upgraded.
