There are errors in lines at the end of your sources.list

open a terminal (ctrl-alt-t) and issue the command

gksudo gedit /etc/apt/sources.list

you will be asked for your password (please enter it when asked so) and will then open an editor with your soucres listed loaded.

Youe have to replace the lines that currently read

by these lines:

Then save the file and close the editor, and retry with update-manager

Tried your suggestion,still no go.any other ideas,i could try ??? Thanks

What is the result of the following:

open a terminal (ctrl-alt-t) and issue the command

sudo apt-get update

you will be asked for your password (please enter it, and note that you will not get any feedback, no echo, not even '*' placeholders).
When the command has finished please select all output (edit - select all), copy it (edit - copy) and paste it into a new message of this question thread.

E: Malformed line 59 in source list /etc/apt/sources.list (dist parse)
E: The list of sources could not be read.

Please open a Terminal window (Ctrl+Alt+T) and run this command:

lsb_release -a; echo; cd /etc/apt; ls -l sources.list.d; echo; cat sources.list

To do that, select the command (if it's split into two lines in your email, select it at https://answers.launchpad.net/ubuntu/+source/apt/+question/166550 instead), copy it to the clipboard, then paste it into the Terminal and press enter to run it.

That will, among other things, provide information revealing whether or not there were any problems in your editing of the configuration file.

Then select all the text in the Terminal (Edit > Select All), copy it to the clipboard (Edit > Copy), and paste it here.

The output does not contain all information as requested, please issue the command

cat /etc/apt/sources.list

That is very unusual output for the command I gave you, though it is expected output if you left something off the end of the command I gave you. Unfortunately, since you did not provide *all* the text from the Terminal (as I had requested), I cannot know for sure what went wrong. Did you perhaps also neglect to my advice about copying it from https://answers.launchpad.net/ubuntu/+source/apt/+question/166550 if it was split into two lines in your email?

It looks like you never edited /etc/apt/sources.list. Did you follow Manfred Hampl's instructions in post #3 (as numbered at https://answers.launchpad.net/ubuntu/+source/apt/+question/166550)?

Yes I have already tried the same,,but issue still remains,can you provide me with any alternatives i could try ???

Can you follow the instructions as given above, or is there a problem when trying so?
Do you see error messages?

I have tried all the steps as stated above & no it does not give any error messages,i get the error message only when i try to use the update manger or the software sources or try to Open the Synaptic Packet manager,could you tell me what exactly is the problem with my system ???

Ok, then try again:

open a terminal (ctrl-alt-t) and issue the command

gksudo gedit /etc/apt/sources.list

you will be asked for your password (please enter it when asked so) and will then open an editor with your soucres listed loaded.

In the editor window scroll down to the end and delete the last lines that read as follows:

deb http://archive.ubuntu.com/ubuntu maverick main multiverse universe
deb http://ppa.launchpad.net/synce/ubuntu intrepid main
deb-src http://ppa.launchpad.net/synce/ubuntu intrepid main

deb http://ppa.launchpad.net/synce/ubuntu11.04 main
deb-src http://ppa.launchpad.net/synce/ubuntu11.04 main

when you have deleted these lines save the file and close the editor window.

Then try the command
sudo apt-get update
again, and copy/paste all output that you receive to a new message in this question document as done before

Reading package lists... Done

Hey it worked,The Update manager & the Synaptic manager are working now !!!

What did we do ???

> What did we do ???
We helped you repair the error in the configuration file containing the addresses of the software package servers. The error most probably was created by an attempt to update the link to the synce private package archive.

As the above commands have removed the linkj to the synce ppa, there is one action that you might still want to do to re-add it:
Open a terminal and issue the following command:

sudo add-apt-repository ppa:synce/ubuntu
