No access to Synaptic in Ubuntu 10.10
 

I just made something stupid while downloading Skype, and as a result Synaptic Package manager don't open, it tells me that "gksudo" is unknown on line 1 in sources list and tells me to go there and fix it.Ubuntu software center is equally kicking my ass. I went to /etc/apt/sources list and tried to remove "gksudo... but could not. Can anybody tell me what to do when the message reads: "the list of sources could not be read. Go to the repository dialog to correct the problem". Please tell me step by step. I'm a newbie...

Like what?

You won't be removing gksudo, this is a sudo for the kde environment.

You have probably have an error in your sources list. Could you please post the contents of /etc/apt/sources.list

gksudo gedit /etc/apt/sources.list#deb cdrom:[Ubuntu 10.10 _Maverick Meerkat_ - Release i386 (20101007)]/ maverick main restricted

That's your problem! Remove everything up to the # and save the file. The first line should look like
when you are finished. If you're worried about making a mistake make a copy of the file first!

But how to do it? When I go there, the cursor is "alive and kicking", but the second I try to do anything like going backspace it just dies and stays immovable, if I paint part of the text beginning with "gksudo..." blue in order to delete that part, nothing happens.
Give me a hint, please.

I managed to get the text changed, but I was told that I have not the right to save any changes that I did, so what now???

You need to have root privileges to edit the file.

Do
To open gedit as root. Edit and save.

Thank you, my friend. Everything seems OK now!
