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.
