[Bug 138853] Re: package flashplugin-nonfree 9.0.48.0.0ubuntu9 failed to install/upgrade: subprocess post-installation script returned error exit status 2

[^rooker]

I'm still receiving this error on Gutsy - even with the
/usr/lib/midbrowser/plugins directory created:

Preparing to replace flashplugin-nonfree 9.0.48.0.0ubuntu10 (using .../flashplugin-nonfree_9.0.48.0.0ubuntu10_i386.deb) ...

E: Sub-process /usr/bin/dpkg returned an error code (1)
----------------------------------

I can neither remove nor reinstall this plugin - furthermore, this error
causes the packages "firefox" and "konqueror" to fail upon upgrade, too.
