Currently, I am using Ubuntu 12.10. When I open Software Updates, I find new release Ubuntu 13.04 rather than Ubuntu 14.04.

Please Help!

  • Ignore my earlier comment which I've now deleted. 12.10 is still a supported release, but only for the next few days - probably why you're trying to upgrade. – thomasrutter Apr 28 '14 at 05:19
  • Because some of my windows problem I cant install ubuntu alongside windows 8. The only version I can install successfully is 12.10. So I need to upgrade it. – KUSHAL Apr 28 '14 at 05:19
  • Did you look at the ubuntu.com website concerning upgrade installs? This type of information is documented there in great detail. – mdpc Apr 28 '14 at 06:34

It is not possible to upgrade from 12.10 to 14.04. Instead you will need to upgrade to the versions in between, in turn. This means you'll need to upgrade first to 13.04, then 13.10, then 14.04.

The available upgrade paths between Ubuntu versions can be described like this:

  • You can upgrade from any version to the immediate next version.

  • If you have an LTS version you can also elect to upgrade to the next LTS version, skipping the versions in between the LTS versions.

If you are on a non-LTS version (such as 12.10) your only upgrade path is to the immediate next version. To reach subsequent versions you must do multiple upgrades. Or you could do a fresh install.

You have upgrade to 13.04, 13.10 then to 14.04. If you want directly Ubuntu 14.04, download Ubuntu 14.04 , make it usb/disc bootable with 14.04 then select Upgrade to Ubuntu 14.04. This will upgrade whole Ubuntu except for /home directory (as it contains user data).

This will install fresh copy of whole Ubuntu, so before that backup your installed Softwares/packages & configurations with the help of this post. here

OR else just use this software Aptik to avoid commands.

As per comments, do this Upgrade to Ubuntu 14.04. As you have downloaded Ubuntu 14.04 LTS, make a DVD or USB bootable. This can be done with many different softwares. One of them is Unetbootin. Select your platform on which you will be using this software to make USB/DVD bootable. Then follow this video.

After making usb bootable restart your pc & go to BIOS or else just press F11/F12 & select your pendrive name & select Boot Priority Device as your Pendrive.

Ubuntu 14.04 will start then select Install Ubuntu then after selecting place,keyboard settings(default), username & password, select Upgrade to Ubuntu Trusty Tahr 14.04.This will upgrade your Ubuntu to 14.04. Now everything will be erased except for /home directory. Then again restore apps by following this post again.

Hope this helps!

  • That second method is more of a fresh install than an upgrade. If "Upgrade to Ubuntu 14.04" is what that option is called on the bootable install disc then that seems misleading to me - as it would wipe your entire install (including software selections and system-wide configuration) apart from the contents of your home directory. – thomasrutter Apr 28 '14 at 07:26
  • neon_overload yes sir,softwares will be deleted but you can take backup of installed softwares/packages & their settings. I have edited my answer as I forgot to mentioned it. – Deepen Apr 28 '14 at 07:41
