Please help, the following is the message I am getting from the update manager when I try to start it:

You have already posted the reason:


'E:Line 1 too long in source list /etc/apt/sources.list.d/medibuntu.list.'

[Old_Grey_Wolf]

please help me out . ...

'E:Line 1 too long in source list /etc/apt/sources.list.d/medibuntu.list.'
.

Remove the offending file
sudo rm /etc/apt/sources.list.d/medibuntu.list

Then add the medibuntu repository back

sudo wget http://www.medibuntu.org/sources.list.d/$(lsb_release -cs).list \--output-document=/etc/apt/sources.list.d/medibuntu.list &&
sudo apt-get -q update &&
sudo apt-get --yes -q --allow-unauthenticated install medibuntu-keyring &&
sudo apt-get -q update

Thanks! This worked for me! Before, I had tried running "sudo apt-get update", and this was the output:

And the output of "sudo apt-get upgrade":

When I ran

sudo rm /var/lib/apt/lists/* -vf
it complained

rm: cannot remove `/var/lib/apt/lists/partial': Is a directory
but it still worked, even without removing this directory.

Thanks a ton!
