I had a similar issue on lubuntu 12.04 while trying to install "ttf-mscorefonts-installer": it hangs for a while after "ttf-mscorefonts-installer: downloading http://downloads.sourceforge.net/corefonts/andale32.exe"; and then it ended giving the same error reported here, with the only difference that in mine it put "ttf-mscorefonts-installer" in place of "flashplugin-installer".
I successfully solved the issue by installing "libgtk2-perl". -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/987965 Title: notifier 'Failure to download extra data' every kubuntu 12.04 restart To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/update-notifier/+bug/987965/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
