"E: The list of sources could not be read." while trying to update [duplicate]

When I try to update, I get this:

root@deepit-R405-A-CPD6A2:/var/lib/apt# sudo apt-get update
E: Type '123443215' is not known on line 61 in source list /etc/apt/sources.list
E: The list of sources could not be read.

Any idea what I can do?


You need to edit the file /etc/apt/sources.list and fix (at least) line 61 of it. You can edit it by opening a terminal window and doing:

gksu gedit /etc/apt/sources.list

You can comment out that line by putting a # at the start of the line.
