Comment 5 for bug 694391

This problem still exists in 4.0~b8+nobinonly-0ubuntu2.

Note, my testing process is the following:

sudo apt-get purge firefox*
sudo apt-get autoremove
sudo apt-get autoclean
sudo apt-get install kubuntu-firefox-installer

Then run:kubuntu-firefox-installer

that fails with the same error message as earlier. An 'apt-get install -f' gives the following:

sudo apt-get install -f
