In this article, we’re going to explain how to upgrade to Ubuntu 14.10 from the older releases of Ubuntu.

There are 2 ways for upgrading to Ubuntu 14.10 from the older releases; via GUI and from the command line, we’ll explain both.

Warning: We highly urged that you take backup of your important files before doing a upgradation of your system, and also read release notes for more information before upgrading to latest version.

Upgrade Ubuntu 14.04 to 14.10

But first, there’s a simple common step between both ways, we have to update our update-manager settings, so that our system be able to discover any new available versions, not only the LTS releases. So, open your dash window and search for “Software & Updates” and open it.

Switch to the “Updates” tab, and change “Notify me of new Ubuntu version” from “For long-term support versions” to “any newer version” as you can see in the screenshot.

Write your password and prepare to upgrade to Ubuntu 14.10 using one of those ways.

Upgrade to Ubuntu 14.10 from the GUI

This will be a good choice for people who don’t want to use the command line (though it’s much easier) and who want to do-the-thing using the graphical user interface only.

First, we have to upgrade some packages, you may do it from the Software Updater, but it is quicker via terminal, so open your terminal and write.

$ sudo apt-get update
$ sudo apt-get dist-upgrade

Note: The upgrade process may take some time depending upon your Internet speed. Once upgrade process completes, open your dash window, and search for “Software Updater”.

    Hi there

    I’ve gone through the stages you’ve described here, but I keep getting an error message: ‘

    Checking for a new Ubuntu release
    Get:1 Upgrade tool signature [198 B]
    Get:2 Upgrade tool [1,147 kB]
    Fetched 1,148 kB in 6s (77.0 kB/s)

    Debug information:

    gpg: Can’t check signature: public key not found

    Authentication failed
    Authenticating the upgrade failed. There may be a problem with the network or with the server.

    I am using a pitifully slow public wifi in my local library – could that have something to do with it?

    You have a typo in your how-to:

    sudo do-release upgrade

    Should be:

    sudo do-release-upgrade
