Upgrading Ubuntu is very easy! Even a novice user can easily upgrade Ubuntu from one version to another in the first attempt itself. That's why I always recommended Ubuntu for newbies who wants to try Linux for the first time. However, a developer has made the upgrade process a lot easier than ever. Meet zzupdate, a simple command line utility to fully update an Ubuntu PC/server via apt, mostly hands-off and unattended. Believe me or not, You can now upgrade your Ubuntu, either Desktop or Server edition, with a single command. I tested this script in Ubuntu 18.04 LTS and it worked just fine as described below. Read on.
Features
- Automatic unattended upgrade.
- User intervention or any coding knowledge is not required.
- Easy to install and use. Just download and start using it in no time.
- Free and open source. The source code is freely available in GitHub.
Upgrade Ubuntu With A Single Command Using zzupdate
The official and recommended way to upgrade any Ubuntu version to the next available version is to run the following commands one by one and follow the onscreen instructions.
For Ubuntu Desktop:
$ sudo apt-get update
$ sudo apt-get dist-upgrade
$ sudo reboot
$ sudo update-manager -d
For Ubuntu Server:
$ sudo apt-get update
$ sudo apt-get upgrade
$ sudo apt-get dist-upgrade
$ sudo reboot
$ sudo do-release-upgrade -d
However, you don't need to run all those commands to upgrade Ubuntu. The zzupdate upgrades any Ubuntu version in a single command.
First, open up the Software & updates either from Gnome Dash or application launcher.
In the Software & updates wizard, go to Updates section and choose the version type you want to upgrade.
If you want to upgrade the current Ubuntu version to any available new version (LTS or non-LTS), choose “For any new version” from the “notify me of new Ubuntu version” drop down box.
If you want to upgrade the current Ubuntu version to next available LTS version only, choose “For long-term support versions” from the “notify me of new Ubuntu version” drop down box in the Updates section.
Once you have chosen the version type, close the "Software & Updates" window.
Next, download "zzupdate" utility using command:
$ curl -s https://raw.githubusercontent.com/TurboLabIt/zzupdate/master/setup.sh | sudo sh
Sample output would be:
[...] Installing... ------------- Cloning into 'zzupdate'... remote: Counting objects: 96, done. remote: Total 96 (delta 0), reused 0 (delta 0), pack-reused 96 Unpacking objects: 100% (96/96), done. Already up to date. Setup completed! ---------------- See https://github.com/TurboLabIt/zzupdate for the quickstart guide.
Then,run the following command to upgrade Ubuntu:
$ sudo zzupdate
It's that simple. You don't need to do anything. zzupdate will take care of everything and upgrade your current Ubuntu version to next available version.
Once the upgrade process is completed, Zzupdate will automatically reboot your system to newly upgraded system.
Here is the my Ubuntu 18.10 desktop after upgrading from Ubuntu 18.04 LTS:
Note for those who updating their Ubuntu via SSH session:
In case you’re upgrading via SSH, it is recommended to start the upgrade process within screen session. Because in case of any SSH connectivity failure during upgrade process, you can easily reconnect with the upgrade session.
To install the screen tool, run:
$ sudo apt-get install screen
Then start the screen session using command:
$ screen
In case of any connectivity failure, you can re-attach to the upgrade session with command:
$ screen -Dr
Now, run the following command to upgrade Ubuntu:
$ sudo zzupdate
Configure zzupdate
zzupdate works just fine out of the box. However, if you want to change some parameters (such as, to exclude reboot, version aggression), you're free to do that by modifying the config file.
Copy the default config file:
$ sudo cp /usr/local/turbolab.it/zzupdate/zzupdate.default.conf /etc/turbolab.it/zzupdate.conf
Edit the configuration file:
$ sudo vi /etc/turbolab.it/zzupdate.conf
Then, modify the parameters as per your requirement.
Here is the list of available parameters.
- REBOOT - If the value is 1, the system will be restarted at end of the upgrade process. Default is 1.
- REBOOT_TIMEOUT - Reboot default time out value. Default value is 15.
- VERSION_UPGRADE - If the value is 1, it executes version progression if a new version of Ubuntu is available.
- VERSION_UPGRADE_SILENT - If the value is 1, version progression occurs automatically, without asking the user anything. Default value is 0.
- COMPOSER_UPGRADE - If the value is 1, it automatically upgrades composer.
By default, we run "zzupdate" to upgrade Ubuntu with default parameters. We can also create different profiles with specific parameter(s).
To do so, create a specific profile by copying from the default config file:
$ sudo cp /usr/local/turbolab.it/zzupdate/zzupdate.default.conf /etc/turbolab.it/zzupdate.profile.ostechnix.conf
Please note that, I have used "ostechnix" in the profile name.
Then, modify the default available parameters as per your requirement.
$ sudo vi /etc/turbolab.it/zzupdate.profile.ostechnix.conf
REBOOT=0 REBOOT_TIMEOUT=10 VERSION_UPGRADE=1
Save and close the file. Now, you can start the upgrade process using the specified profile name as shown below.
$ sudo zzupdate ostechnix
Similarly, you can create as many as profiles with different parameters.

is this command only for 17.04? or any futuristics LTS?
It is for all Ubuntu versions.
Thx for reply. The name of command is zzcommand (zz–>zesty zapus), so I understood this cmd is upgrading from any version (15.10 or 14.04 ) to zesty (source –> many, but destination –> one and only one zesty)
Thanks for your review!
