### What Is zzupdate?
|
||||
|
||||
We can upgrade Ubuntu PC/Server from one version to another version with just a single command using [zzupdate][2] utility. It’s a free and open source utility and it doesn’t required any scripting knowledge to work on this because it’s purely configfile-driven script.
|
||||
|
||||
There were two shell files are available in the utility, which make the utility to do the work as expected. The provided setup.sh auto-installs/updates the code and makes the script available as a new, simple shell command (zzupdate). The zzupdate.sh will do the actual upgrade from one version to next available version.
|
||||
|
||||

||||

### How To Configure zzupdate [optional]
|
||||
|
||||
By default zzupdate works out of the box and no need to configure anything. It’s optional and if you want to configure something yes, you can. To do so, copy the provided sample configuration file `zzupdate.default.conf` to your own `zzupdate.conf` and set your preference.
|
||||
```
|
||||
$ sudo cp /usr/local/turbolab.it/zzupdate/zzupdate.default.conf /etc/turbolab.it/zzupdate.conf
|
||||
|
||||
```
|
||||
|
||||
Open the file and the default values are below.
|
||||
```
|
||||
$ sudo nano /etc/turbolab.it/zzupdate.conf
|
||||
|
||||
REBOOT=1
|
||||
REBOOT_TIMEOUT=15
|
||||
VERSION_UPGRADE=1
|
||||
VERSION_UPGRADE_SILENT=0
|
||||
COMPOSER_UPGRADE=1
|
||||
SWITCH_PROMPT_TO_NORMAL=0
|
||||
|
||||
```
|
||||
|
||||
* **`REBOOT=1 :`**System will automatically reboot once upgrade is done.
|
||||
* **`REBOOT_TIMEOUT=15 :`**Default time out value for reboot.
|
||||
* **`VERSION_UPGRADE=1 :`**It perform version upgrade from one version to another.
|
||||
* **`VERSION_UPGRADE_SILENT=0 :`**It disable automatic upgrade perform version upgrade from one version to another.
|
||||
* **`COMPOSER_UPGRADE=1 :`**This will automatically upgrade the composer.
|
||||
* **`SWITCH_PROMPT_TO_NORMAL=0 :`**If it’s “0” then it looks for same kind of version upgrade. If you are running on LTS version then it will looking for LTS version upgrade and not for the normal release upgrade. If it’s “1” then it looks for the latest release whether you are running an LTS or a normal release.
