Comment 7 for bug 979477

Hi. I was having this problem before I updated to "update-notifier - 0.119ubuntu7", but it seems like the problem is still there for me even after the update. I just installed yesterday Ubuntu Server 12.04 beta 2 64 bit + kubuntu-desktop on top of it. Got the same message window "packages requested additional data downloads after package installation, but the data could not be downloaded" for ttf-mscorefonts-installer and also flashplugin-installer when trying to install kubuntu-restricted-extras from the Muon Package Manager.
When I press "Run this action now" in the message window, a bash shell opens up with the following lines:

Warning: Could not find 'gksudo', starting '/bin/bash' instead. Please check your profile settings.

The "Run this action now" button is grayed out after that, and the message window stays there until I press "Close" in it. Ttf and Flash are not installed after that. Reinstall from Muon repeates this message.

Here are some lines from /var/log/apt/term.log related to ttf and flash plugin:

-----------------

I use a direct access to the Internet, no proxies.
So, is it still Bug #979477, or similar Bug #977178 , or maybe something new? Any ideas on how I should proceed with the installation?
