Hello, I've got a big problem in regard to my sources.list
when I write the command leafpad etc/apt/sources.list it comes out an empty sources.list.... and when I check in the computer (folders - etc/apt - and the file) the sources.list is not empty...

Moreover, when I try to put any repository inside.. it comes out to save this file... when I save it.. after that is the same and the leafpad /etc/apt/sources.list is empty again and gives me to save again the file...

I don't know what happened, it was working perfectly fine when I change the repository at the first place, but know the sources.list is empty... I tried to delete my virtual box and Kali from everywhere and install it again, but the sources.list is still empty.
Please someone to help me
