W: Target packages errors

[Moltke]

[member=5666]csias40[/member] You seem to have the google earth and google earth pro repo multiple times on your sources list, so you need to edit one of those and comment it, for that, open a terminal and type:

Code:

sudo nano /etc/apt/sources.list.d/google-earth.list

or

Code:

sudo nano /etc/apt/sources.list.d/google-earth-pro.list

It's up to you to decide which one you want/need. Place a "#" symbol in front of the line that begins with deb, like

Code:

#deb http://dl.google.com/linux/earth/deb/ stable main

or

Code:

#deb http://dl.google.com/linux/earth-pro/deb/ stable main

Then try to update again and everything should be fine.

Hope this helps!
