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


Solution 1:

Close all programs/windows which have to do with installing software e.g. Synaptic, software-centre and terminals.

Now you should delete the locked files:

You can delete the lock file with

sudo rm /var/lib/apt/lists/lock

you may also need to delete the lock file in the cache directory

sudo rm /var/cache/apt/archives/lock 

by: this answer

and now you should open a terminal and run:

 sudo apt-get update --fix-missing

and now you can install everything you want again.

Solution 2:

It could be the case that you are connecting to the Internet via a proxy so you should set up the proxies for apt-get by doing the following:

  • create a folder in /etc/apt/apt.conf.d/

    $ sudo leafpad /etc/apt/apt.conf.d/95proxies
    
  • In side the opened file paste the following:

    Acquire::http::proxy "http://yourProxyIP:8080/";
    Acquire::ftp::proxy "ftp://yourProxyIP:8080/";
    Acquire::https::proxy "https://yourProxyIP:8080/";
    

Make sure to change yourProxyIP with a correct proxy IP.

Save the file by hitting Ctrl+S Then run:

sudo apt-get update.
