duplicate error messages opening synaptic

[Datchew]

using the ubuntuguide.org method of copy/pasting my way to enable extra repositories, i ended up now getting these little popup errors every time i open synaptic package manager.

how can i get rid of them?

You probably have a line like this

deb http://archive.ubuntu.com/ubuntu/ warty main restricted

and another like this

deb http://archive.ubuntu.com/ubuntu/ warty main restricted universe multiverse

in /etc/apt/sources.list. But this means "main" and "restricted" are listed twice.
If this is the case, you can delete (or comment out with a #) the first line.

hmmm... yes, i found duplicates.

i was trying to find duplicates inside the preferences -> repositories of synaptic manager but couldn't.

i #'d out the duplicates.
that seems to have done it.
thanks much.

nice to finally have an EASY fix.
