Trouble apt-get install dosemu-freedos

Using a newly installed Kubuntu Gutsy Gibbon.

First, I did
apt-get install dosemu

It seemed to install.

The old settings for dosemu were already in my home directory which was not changed by the install.

I noticed that, although dosemu came up properly, I could not exit with 'exitemu'.

Eventually I did alt-F4 to exit.

Next I removed dosemu with
apt-get remove dosemu.

Then I tried
apt-get install dosemu-freedos
and was told there are unmet dependencies.

I did not install the xfonts-terminus-dos package.

What am I doing wrong? Do I need to add a DEB repository?
