One command makes Ubuntu upgrade easier

zzupdate[1] is an open source command line program that makes the task of upgrading Ubuntu desktop and server versions to a newer version easier by combining several update commands into a single command .

Upgrading your Ubuntu system to a newer version is not a difficult task. Whether using the GUI or using a few commands, you can easily upgrade your system to the latest version.

On the other hand, Gianluigi 'Zane' Zanettini wrote zzupdate with just one command to clean, update, auto-remove, version upgrade, self-update of the tool in Ubuntu.

It cleans the local cache, updates available package information, and then performs a release upgrade. Next, it updates the tool and removes unused packages.

This script must be run as the root user.

Install zzupdate to upgrade Ubuntu to a newer version

To install zzupdate, execute the following command in the terminal.

curl -s https://raw.githubusercontent.com/TurboLabIt/zzupdate/master/setup.sh | sudo sh

Then copy the provided sample configuration file to zzupdate.conf and set your preferences.

sudo cp /usr/local/turbolab.it/zzupdate/zzupdate.default.conf /etc/turbolab.it/zzupdate.conf

Once completed, just use the command below and it will start upgrading your Ubuntu system to a newer version (if one is available).

sudo zzupdate

Please note that in normal versions (non-LTS versions), zzupdate will upgrade the system to the next available version. However, when you run Ubuntu 16.04 LTS, it will try to search only for the next long-term support version, not the latest version available.

If you want to exit the LTS version and upgrade to the latest version, you will need to change some options.

For Ubuntu Desktop, open Software and Updates and under the Updates tab, and change the Notify me of new Ubuntu versions option to "For any new versions".

Software Updater in UbuntuFor Ubuntu service releases, edit the release-upgrades file.

vi /etc/update-manager/release-upgrades

Prompt=normal

Configuration zzupdate [optional]

zzupdate Options to configure:

REBOOT=1

If the value is 1, the system will restart after the upgrade.

REBOOT_TIMEOUT=15

Set the reboot timeout to 900 seconds because some hardware takes longer to reboot than others.

VERSION_UPGRADE=1

If an upgrade is available, perform a version upgrade.

VERSION_UPGRADE_SILENT=0

Automatically display version progress.

COMPOSER_UPGRADE=1

A value of "1" will automatically upgrade the tool.

SWITCH_PROMPT_TO_NORMAL=0

This feature updates the Ubuntu version to the stock version, i.e. if you are running an LTS distribution, zzupdate will not upgrade it to Ubuntu 17.10 (if it is set to 0). It will only search for LTS versions. In contrast, "1" will search for the latest version, whether you're running LTS or stock.

Once completed, all you have to do is run a full Ubuntu system update in the console.

sudo zzupdate

Final words

Although the Ubuntu upgrade process itself is simple, zzupdate reduces it to a single command. No coding knowledge is required and the process is entirely profile driven. I personally find this to be a great tool for updating several Ubuntu systems without having to worry about different things individually.

Are you willing to try it?
