Sparebank1 Nettbank on Ubuntu Lucid (10.04)

In case anyone else is having the same problem as I did with Sparebank1 Nettbank after upgrade to Ubuntu Lucid. Here's how to fix it:

echo "deb http://archive.canonical.com/ubuntu lucid partner" >> /etc/apt/sources.list
sudo apt-get remove icedtea6-plugin
sudo apt-get install sun-java6-plugin
