Hello, all,
	I'm trying to install gnome, but got a /var/cash... error.  So,
I tried changing the cache-size, and ended up having to apt-get -f
install.  Now, I'm getting the following error:
  libx11-6 libxt6
0 upgraded, 2 newly installed, 0 to remove and 1 not upgraded.
370 not fully installed or removed.

Do you want to continue? [Y/n] y

	What should I do about this?

Thanks,
