Versions of Ubuntu are traditionally timed to releasesGNOME (about a month), which, in turn, are released about a month after the release of X.Org. As a result, in each release of "Ubuntu" there is a new version of GNOME and X.

Every fourth issue, issued in the secondquarter of every even year, acts as a distribution with long-term support. This means that these OS releases are evolving and getting updates for five years and have technical support from Canonical Ltd. These include versions of Ubuntu 6.06, 8.04, 10.04, 12.04, 14.04 and 16.04. However, all distributions that came out before "Ubuntu 12.04"? were supported only for only three years.

Other versions released before 13.04, as a rule, were supported for 18 months and usually did not turn out to be obsolete until the next "long-playing" distribution. This has changed, however, since Ubuntu13.04 - the support period has been reduced by half, to 9 months.

Most users are interested in having an updated and up-to-date OS on their device. How does the Ubuntu version update?

First of all, you must remember thatAny upgrade associated with the major releases of the operating system carries the risk of failure, data loss, or broken software configuration. Complex backup and extensive testing is strongly recommended in any case, even if you are an advanced user.

The following guide assumes that your device is running on Ubuntu 15.10, configured with Sudo privileges for administrative tasks.

Although many systems can be updatedinstantly without any difficulties, a safer solution is to go to the boot file of the new version, installing the distribution from scratch and performing the configuration of services with thorough testing and import of application data as a separate step.

What do I need to know before updating?

Keep in mind that libraries, languages, and systemservices can significantly change. In Ubuntu 16.04 there have been important changes, compared to the previous release of LTS, which include the transition to the initialization of Systemd instead of Upstart, and the emphasis on supporting Python 3 and PHP 7 instead of PHP 5.

Before embarking on a major modernization inany system, you need to make sure that you do not lose data if the update goes wrong. The best way to achieve this is to make a backup of the entire file system. Using Digital Ocean Droplet, you can use the simplest approach - turn off the system and make its image.

Before you start the update, it's safer to install the latest versions of all the packages for the current version. Start by updating the package list: Sudo update APT-Get.

You will be shown a list of updates thatpossible to do. Select the answer "yes" and press Enter. This process may take some time. After its completion, use the Dist-Upgrade command, which will perform updates related to changing the settings, adding or removing new packages as needed. For all system requests, answer "yes" and wait until the process is complete.

Now that you have the latest updates forUbuntu 15.10, you can replace the OS with version 16.04. Download the tool to perform updates "Ubuntu". To do this, run the following command: sudo apt-get update.

Traditionally, Debian releases have been endowed withthe ability to expand by changing the /etc/apt/sources.list APT, which defines package repositories. Ubuntu still works on the principles of Debian, so this process, most likely, still works without difficulties. Instead, however, it is desirable to use the tool provided by the Ubuntu project, which processes all checks for the new version, updates the sources.list, and performs a number of other tasks. This is the officially recommended way to upgrade the server, which must be performed through a remote connection.

Start by running the update without any options: sudo apt-get dist-upgrade.

If you are connected to your system via SSH (most likely you have a Digital Ocean Droplet), you will be asked if you want to continue. At the command prompt, type Y and press Enter to continue.

Further you can be warned that the recordmirror was not found. On Digital Ocean systems, you can safely ignore this warning and continue the update, since the local mirror for 16.04 is actually available.

You will be asked "Do you want to overwrite the file" sources.list "?" If you select "Yes", the operating system will be completely updated. If you select No, the update will be canceled.

After the new lists of packages are downloaded and the changes are tested, you will be prompted to start the update. Press Y to continue.


Installing the update may take several hours. After the download is finished, the process can not be canceled.

After the new packages have completed theiryou will receive a question whether you are ready to remove obsolete packages. On the command line without a user-defined configuration, this procedure must be secure. Click "yes". If you have updated the entire system to a large extent, you can enter d and check the list of packages that will be deleted.

Finally, if everything went well, you will be informed that the update is complete and you need to reboot. Enter Y to continue.


Wait until the computer is rebooted andreconnect. When you boot the system, you should see a message confirming that you are currently migrating to Xenial Xerus Ubuntu (stable version with support).

Now you must configure the working installation of Ubuntu 16.04. You will probably have to investigate the necessary configuration changes to services and deployed applications.
