Where is this " /etc/apt/sources.list " in my windows
 

hello
I'm still having problems.
I use virtual Box and i have ubunto in that.
When I search in google about update not working, I always see the answers about " /etc/apt/sources.list ".
Where is this " /etc/apt/sources.list " in my windows?
How can I find it???

thanks.

Open a terminal and type:
and there it is!
:D

You can also "find" it by opening up your file manager and going to "file system" and then the "etc" folder, then the "apt" folder, then the "sources.list" file will be there -- it is just a text file.

To edit it you will need to open an editor as root using `sudo`
Use <Ctrl>+x to exit, then press "y" and Return to save the modifications.
