System Notification Warning: flashplugin-installer could not be processed

[Gert Brinkmann]

Upgrading the flashplugin-installer had a problem with downloading the flash-tar-file. Because it took very long I have interrupted it and retried again with AFAIR "apt-get -f install". The plugin was successfully updated then.

But: Everytime I log into KDE I see a system notification "Update Information":

"Data files for some packages could not be downloaded

The following packages requested additional data downloads after package installation, but the data could not be downloaded or could not be processed...flashplugin-installer... This is a permanent failure that leaves the packages unusable on your system. You may need to fix your internal connection, then remove and reinstall the packages to fix this problem".

So I tried to "apt-get purge flashplugin-installer" and reinstalled it again "apt-get install flashplugin-installer". But the warning still persists. (Although flash does work fine in e.g. firefox.)

How can I get rid of this warning?

Thanks,
Gert

I ran into this problem again. Removing the file
/var/lib/update-notifier/user.d/data-downloads-failed-permanently
seems to stop the occurence of the notification.
