linuxsoom, Could you describe the steps you took when this error occurred. It looks like you have an invalid sources.list file. Have you edited this file manually or changed it in some way. It seems that all of the # symbols have been removed. All of the lines that DON'T start with 'deb' should have a # symbol at the start to mark them as comments. Because those are missing the package manager is trying to interpret those lines as repositories and failing.
You can either manually replace the # symbols or replace the whole file. If you look in the folder /etc/apt you should see a file named sources.list.orig this is a default sources.list file for ubuntu. If you remove your existing sources.list file and then run the following command it should solve the problem: sudo cp /etc/apt/sources.list.orig /etc/apt/sources.list This just copies the default file in place of your corrupted file. Hope that helps.
