Update An Existing Installation

Despite which distribution you have your EGroupware instance installed on, it's always good idea to run update frequently in order to get the latest update patches and security fixes.

IMPORTANT: Before persuing update procedures we highly recommend you to make a backup from your EGroupware instance.Here is backup procedure.

Please select the distribution from the below list and follow its update instruction.

Ubuntu/Debian

CentOS/RedHat

openSUSE/SLEs

Ubuntu/Debian

Manual Update

1- apt update
You may run command apt list --upgradable in order to see list of packages which will be upgraded.
2- apt upgrade

Automatic Update

1- apt install unattended-upgrades
after installing unattended-upgrades you need to add egroupware packages into list of allowed packages in 50unattended-upgrades file.
2-vi /etc/apt/apt.conf.d/50unattended-upgrades

EGroupware	Ubuntu	Debian
EPL	find the `Unattended-Upgrade::Allowed-Origins` and add the following line: `"stylite-epl:";`	find the `Unattended-Upgrade::Origins-Pattern` and add the following line: `"o=obs://build.opensuse.org/stylite-epl/Debian_8.0,a=";`
CE	find the `Unattended-Upgrade::Allowed-Origins` and add the following line: `"eGroupWare:";`	find the `Unattended-Upgrade::Origins-Pattern` and add the following line: `"o=obs://build.opensuse.org/server:/eGroupWare/Debian_8.0,a=";`

(You need to replace the Debian version according to your used version / repository.)

3- check if the unattended-upgrades with configure packages:
unattended-upgrades --dry-run --debug
--dry-run: only downloads the upgradable packages but will not install them unless you run the unattended-upgrades command with no parameter.
If you wish to check logs and see what has happened with packages, you may read the following logs:

/var/lib/unattended-upgrades/unattended-upgrades.log
/var/lib/unattended-upgrades/unattended-upgrades-shutdown.log
/var/lib/unattended-upgrades/unattended-upgrades-dpkg.log

4- unattended-upgrades will be scheduled for automatic updates and will run automatically, so, from now on you don't need to be worry about out-dated packages.
