14.0414.10upgrade
I can't upgrade from 14.04.1 to 14.10 because when I go into software updater, there is no "upgrade button" available. It just tells me the software is up to date and I click okay to close the window or I can click settings, neither of which help me upgrade.
Anybody got a fix or workaround?
I think the answer is in the first screenshot you sent: "A previous upgrade which didn't complete". Could you open a terminal and issue:
$ sudo apt-get update
$ sudo apt-get upgrade
If it shows error (you may) run
$ sudo apt-get -f install
or
$ sudo dpkg --configure -a
depending on the type of problem that apt found (it will suggest you what to pick). Sometimes the Software Updater is not enough to fully upgrade packages.
In any doubts just post it here.
To upgrade from one version to another, first you need to prepare your system, I mean, updating and upgrading. If not, you wont be able to upgrade.
System preparation
Just in case repositories are disabled (if they are, you wont be able to update), go to
Main Menu: System > Administration > Software Sources.
It will display you a window, that must look like this one.
Tick all of em like in the pic!
Now we are going to update the system.
Be sure you have conection to internet, and open a terminal prompt (ctl + alt + T). Run:
sudo apt-get update
Once updating had finished, let's upgrade the system. In the same terminal prompt run:
sudo apt-get upgrade
Wait until the prompt finishes.
Upgrading to 16.04
If all of this worked without erros, you must be able to upgrade to 16.04. In the same terminal prompt, just run:
sudo do-release-upgrade
Now you can sit and relax, the upgrade will take some time.
Best Answer
You have to change the Update mode.
Your system only looking for "LTS" version, so 14.10 is Normal release. There is settings in Ubuntu where can change this version type and mark it to Normal Release. After that you will get the update notification.
