[ubuntu-za] apt sources problem

Hello All,

I get the following errors whenever I do any apt install and also when
I bring up Synaptic. I presume that this is a problem that has been
there ever since I upgraded 10.04 to 12.04. Somewhere I have seen
"apt-get update" as a solution, but the problem persists.

The error:

W: Duplicate sources.list entry ftp://ftp.sun.ac.za/ubuntu/
precise/main i386 Packages
(/var/lib/apt/lists/ftp.sun.ac.za_ubuntu_dists_precise_main_binary-i386_Packages)

(/var/lib/apt/lists/linux.dropbox.com_ubuntu_dists_precise_main_binary-i386_Packages)

The problem does not seem to make any difference to my ability to
install or update any packages, but perhaps it does?

Any suggestions?

Bill
