Running the command sudo apt-get update | grep Ign in bash of my Ubuntu 15.10 I got the following:
Ign http://dl.google.com stable InRelease
Ign http://dl.google.com stable InRelease
Ign http://dl.google.com stable/main Translation-en_US
Ign http://dl.google.com stable/main Translation-en
Ign http://dl.google.com stable/main Translation-en_US
Ign http://dl.google.com stable/main Translation-en
Should I worry about these ignored lists of packages?
Should I worry about duplication of these lists?
How can I fix it?
UPD:
The content of my /etc/apt/sources.list file:

I have two additional repos:
/etc/apt/sources.list.d/google-chrome.list
/etc/apt/sources.list.d/google-earth.list
The content of first one is
deb http://dl.google.com/linux/chrome/deb/ stable main
The content of the second one is
deb http://dl.google.com/linux/earth/deb/ stable main
If I comment the last string then the duplication disappears. Thus, I guess, there is no problem with the duplication.
/etc/apt/sources.listto get a clue. – DK Bose Feb 10 '16 at 02:17
