So I've been checking around on how to update my Ubuntu OS from 13.10 to 14.04 LTS, and each thing I see says to use commands in the terminal. Some of the commands I've tried are:

sudo apt-get install update manager-core
do-release-upgrade

and several others. Each time I try I am met with something that says everything is up to date, or in the case of do-release-upgrade I got:

Checking for new Ubuntu release
No new release found

Am I missing something? Is there a file I'm meant to download for this to work, or does it look through the internet for whatever it needs, in which case it is failing to find anything?

So is there any way I can upgrade through this method, as I can't download an .iso as my computer doesn't have a disk drive, nor can I go through a flash drive, as I don't have any that I can use right now?

Test this procedure:

First: You need to update the system.

Open a terminal,

Press Ctrl+Alt+T

Run it:

sudo -i
apt-get update
apt-get dist-upgrade

Reboot your system to finish installing updates, and to upgrade to new available version:

Open a terminal,

Press Ctrl+Alt+T

Run it:

sudo -i
nano /etc/apt/sources.list

In the open file, delete the content and paste this:

deb http://ar.archive.ubuntu.com/ubuntu/ trusty main restricted
# deb-src http://ar.archive.ubuntu.com/ubuntu/ trusty main restricted
deb http://ar.archive.ubuntu.com/ubuntu/ trusty-updates main restricted

Ctrl + O, save file. Ctrl + X, close nano.

Continue run in a terminal:

sudo -i
apt-get clean
apt-get update
apt-get dist-upgrade
apt-get autoremove
apt-get -f install
dpkg --configure -a
apt-get clean
reboot

Try the below command 

sudo do-release-upgrade

The problem may have been because you aren't root.
