No facility exists in Update Manager to upgrade to a new version, why?

Question

I am trying to upgrade to a new Ubuntu version but the update manager does not recognize an update. Why not?

which commands do you use to upgrade? – Hojat Taheri Apr 26 '13 at 05:17 — Hojat Taheri, Apr 26 '13 at 05:17

Because Ubuntu 12.04 is a Long Term Support release (meaning that it is supported with bug fixes and security updates for 5 years) you won’t find a pop-up telling you that a new version is available.

If you want to upgrade,you can follow these instructions

Open Update Manager from either the Power Menu or the Dash.
Click the ‘Settings’ button in the lower-left corner of the Update Manager window: This will open Software Sources.
Click the menu next to “Notify me of a new Ubuntu version” and select ‘For Any New Version’

enter image description here

Important DO NOT uncheck or alter anything other than the above.

Once you’ve made the change you will likely be prompted to input your user password. After this, close Software Sources, then close and then reopen Update Manager.

. Click the ‘Upgrade’ button to begin your upgrade to Ubuntu 12.10.

What can be done so that the new version is also found when using "sudo apt-get dist-upgrade"? I typically use that, not the update manager. But I just checked, the update manager finds 12.10, on the command line it is not found. – Marius Hofert Oct 19 '12 at 13:53

Marius, the 'do-release-upgrade' command is set up for that. 'dist-upgrade' will only upgrade you to a new version if you have also already changed all of your references in /etc/apt/sources.list to the new distro. – AvatarKava Oct 22 '12 at 11:15
Wow, this is surprisingly hard to find, particularly given that you actually have to quit the thing after telling it what you want. And especially on my netbook, where the "settings" button isn't visible because the update manager window is too large for the display. And there is no menu. I wonder what fraction of users are expected to ever upgrade from an LTS to another non-LTS version? – nealmcb Jan 06 '13 at 22:48

You can also force it to check for development versions (since Quantal is released this won't really make any significant difference for you) by opening a terminal and typing:

update-manager -d &

open Software Sources application (you can find it in the Dock) and go to the Updates tab

You should choose the option For any new version

enter image description here

Then press [Alt] + [F2] and type update-manager -d

Update Manager should offer you an upgrade to the new version.

Run this command in the terminal:

sudo do-release-upgrade

That will do the same as running it GUI :)

The easiest way to upgrade from 12.10 to 13.04, just press Ctrl+Alt+T on your keyboard to open Terminal. When it opens, run the command below:

sudo do-release-upgrade -d

Please try this first:

$export DEBUG_UPDATE_MANAGER=1

$do-release-upgrade

Then, it will verbose detail information and possible errors. As in my case, the error is authorization error caused by setting a proxy in Synaptic Manager that need authorization. Disable the proxy solves my problem.

Hope you can find a solution to your problem too.

Thanks - this is exactly what I needed! I ran into an issue with a LAN->wifi adapter not connecting correctly, and this returned an HTML page as a response for the metadata cache. Removing the cached file and re-running do-release-upgrade worked. – Robert Hui Sep 20 '13 at 08:23
