I found a temporary solition. Open your sources.list file with gedit.
sudo cp /etc/apt/sources.list /etc/apt/22.05.2012.sources.list.bak sudo gedit /etc/apt/sources.list
Search independent keyword and comment all lines save and close. Now try sudo apt-get update, it works for me but this changes probably disable major and dist updates.
