Help with an error code : (main/source/Sources) is configured multiple times

I have searched a bit my own, but i haven't been able to fix this.

I just want to say thanks in advance for any help given, and apologize if this is stupid question.

Open a terminal (Ctrl+Alt+t) and enter…

cat /etc/apt/sources.list

Please post the output and your welcome in advance.

Hey v3xx, thank you for your quick reply. I didn't get back to you yesterday because i tried this

Wow is all i can say, and don't try! After i got half way through the 3 commands Caja started opening up window after window after window. It was very odd and struck me as a possible security problem, so after some fiddling i deiced to do a clean install and it happened again with Caja opening up more windows than i could count! Luckily this was not my every day comp and i had an extra SSD because i have some important stuff on one of the other operating systems on that drive. I put that drive in a box for a day when i have more time.

LOL: long story sort , problem solved Cheers :grin: PS: I am using UMATE 16.04 on that machine and one other and it really is solid. I love it!
