Earlier, I had used:

sudo apt-get remove samba

thinking that it will remove samba. But it started uninstalling all my applications including libreoffice, texteditor, java plugin software update manager etc.

And now I am getting error, for the update command

$ sudo apt-get update

E: Some index files failed to download. They have been ignored, or old ones used instead.

Further while trying to install any application, i get the error, in this case for installing vim:-

Reading package lists... Done
Building dependency tree       
Reading state information... Done
Package vim-gnome is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'vim-gnome' has no installation candidate

Any help is appreciated. Thank you

-5 - No address associated with hostname

This error occurs mainly because of invalid or misspelled host name inside /etc/apt/sources.list file.So try the below commands,

sudo rm /etc/apt/sources.list
sudo cp /etc/apt/sources.list.save /etc/apt/sources.list
sudo apt-get update

Note: Before running the above commands please check for /etc/apt/sources.list.save file.If the file was not present then run,

sudo mv /etc/apt/sources.list /etc/apt/sources.list.bak
sudo touch /etc/apt/sources.list
sudo add-apt-repository "deb http://archive.ubuntu.com/ubuntu $(lsb_release -sc) main universe restricted multiverse"

And also enable other software repositories in Software and Updates.Finally run,

sudo apt-get update

Install vim-gnome package by running,

sudo apt-get install vim-gnome
