problem with updating. Could not initialize package information

What is the output of :

cat -n /etc/apt/sources.list

Thanks

acer@acer-Aspire-5315:~$ cat -n/etc/apt/sources.list
cat: invalid option -- '/'
Try `cat --help' for more information.
acer@acer-Aspire-5315:~$

Exuce me but this is the information after I type it on the terminal (cat -n/etc/apt/sources.list)

You missed a space character before the first slash. You better use copy and paste than retyping the command.

If you copy and paste commands, rather than trying to retype them, you are less likely to botch them. It is also why I give the exact command to execute.....

Thanks, now I have this on the terminal. What next?

acer@acer-Aspire-5315:~$ cat -n /etc/apt/sources.list

There is quite some nonsense inside out source.list configuration file. You are missing security updates for the main bucket, and you have several syntactically wrong entries between line 53 and the end.

I recommend you replace your file with contents like this:

Sorry but still nothing happened after I copied and placed this on terminal. Perhaps I am doing it wrongly. How could I replace this?

Sorry, this was a misunderstanding.

Open a terminal and issue the command

gksudo gedit /etc/apt/sources.list
This should ask for your password as confirmation of an administrative task, and should then open an editor with your current sources.list configuration file loaded.

Delete all the contents of the file, and copy/paste the contents from my response into that file.
Save the file and close the editor.

Finally issue the commands

uname -a
lsb_release -a
sudo apt-get update

in the terminal window and copy/paste all output back into this question document.

That should sort it out, your sources.list file is a mess. Looks like you upgraded by using sed to change the sources file and messed up

It works, I have no words to say THANKS A LOT. Great!
