kubuntu-desktop fails to install

Summary: The `kubuntu-desktop' package is present in trisquel repos. However, upon attempting to install it, aptitude fails because the package depends on the nonfree `ubuntu-drivers-common'.

Reproduce steps:

1. Enter terminal
2. Run:
   apt-get install kubuntu-desktop

Expected result:
E: Unable to locate package kubuntu-desktop
, similar to `xubuntu-desktop' and `lubuntu-desktop'
OR
Package installs, ignoring the lack of `ubuntu-drivers-common'

Actual result: aptitude finds package, but fails with:
Depends: ubuntu-drivers-common but it is not installable
