You may already know how to upgrade your Ubuntu desktop to the latest version, but if you use Ubuntu Server and happen to want an upgrade (as long as it doesn't affect your application. Generally speaking, you should adopt a conservative attitude towards the server operating system. If it is not a security problem that must be upgraded to solve, it is best not to upgrade, but to use a variety of external means to solve. )

If you want to upgrade from Ubuntu14.04/13.10/13.04/12.10/12.04 or older to 14.10, just follow the steps given below. Note that you cannot upgrade directly from 13.10 to 14.10. You should upgrade from 13.10 to 14.04 before upgrading from 14.04 to 14.10. Here are the detailed steps.

The following steps can be used not only for 14.10, but also for some Ubuntu derivatives such as Lubuntu14.10,Kubuntu14.10 and Xubuntu14.10

Important: before upgrading, just to be on the safe side, don't forget to save your data on a flash drive or external hard drive.

Server upgrade

To upgrade from a ubuntu14.04 server to a 14.10 server, follow these steps.

Install the update-manager-core package if you haven't installed it before:

The code is as follows:

Sudo apt-get install update-manager-core

Edit the file / etc/update-manager/release-upgrades.

The code is as follows:

Sudo nano / etc/update-manager/release-upgrades

Set up Prompt=normal or Prompt=lts as follows

The code is as follows:

# Default behavior for the release upgrader.

[DEFAULT]

# Default prompting behavior, valid options:

#

# never-Never check for a new release.

# normal-Check to see if a new release is available. If more than one new

# release is found, the release upgrader will attempt to upgrade to

# the release that immediately succeeds the currently-running

# release.

# lts-Check to see if a new LTS release is available. The upgrader

# will attempt to upgrade to the first LTS release available after

# the currently-running one. Note that this option should not be

# used if the currently-running release is not itself an LTS

# release, since in that case the upgrader won't be able to

# determine if a newer release is available.

Prompt=normal

You can now update your service system with the following command.

The code is as follows:

Sudo do-release-upgrade-d

Until the screen prompts you that you have finished.
