dpkg: unrecoverable fatal error, aborting:
 reading files list for package 'texlive-fonts-recommended': Input/output error
E: Sub-process /usr/bin/dpkg returned an error code (2)

before doing this I used this command.

sudo -E apt-add-repository ppa:izx/askubuntu -y

sudo apt-get update results in this error

W: Failed to fetch http://ppa.launchpad.net/izx/askubuntu/ubuntu/dists/trusty/main/binary-i386/Packages  404  Not Found

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

Edit1: I tried to install other packages but that dpkg error keeps showing up.

This is reiterating what the first two replies said, but I've added a few extra steps along with why you're doing them.

First run

 uname - r

to find what kernel version you're using. As the update is reporting that you have an older kernel installed that is no longer required.

The first two listed are programs you no longer need - these can be safely removed, they'll be reinstalled later if they are in fact needed.

Let me repeat, IF, AND ONLY IF, your computer is giving you no problems run 'sudo apt-get autoremove'

The PPA error is saying that either you mistyped the address for the PPA or that the PPA no longer exists. As previously reported, its nit for your version, remive it.

This error can be ignored for the moment, more on this later.

In other words perform the following steps:

uname - r
sudo apt-get autoremove
sudo apt-get autoclean
sudo apt-get install --fix-missing
sudo apt-get update && sudo apt-get upgrade
sudo apt-get dist-upgrade
sudo apt-get install unity-tweak-tool

My original post had a few more steps until I saw that the PPA is not for Trusty.
