Tools > System > Software update

In the update screen you can perform Apresa updates, and configure updates for the Debian operating system.

Apresa updates

Apresa updates are provided during the service period. If the service period has expired, the service period can be extended using a service license key (in the system settings).

Apresa can check for updates online, or you can manually download an update, and upload it to Apresa.

•Online-update: To check for an update online, click the "Check for Update" button. Apresa will need internet access for this to work. A description of the update will be displayed. To execute the update, press the Download button. The update will be downloaded from the Vidicode server and then installed.

•Upload: If you have an update file available, with this option you can manually upload it to the Apresa server. Apresa will not need internet connection in this case. After it is uploaded, the update will be installed. The perform a regular update using the official channel, the update file and change log can be retrieved from the Vidicode server manually.

Debian operation system updates

Debian security updates are provided by the Debian community during the long term support period. When this period has expired for a particular Debian version, security updates are no longer provided.

Automatic security updates: This displays if Apresa is configured to install security updates. In addition, a number of prerequisites needs to be satisfied for updates to be installed:

•Required Debian packages for unattended updates. These can be installed by enabling the Install checkbox.

•Online connection. Apresa needs to have outbound internet access.

•A supported Debian version (long term support period)

•The Debian package system needs to be in a good consistent state. Installing incompatible or broken packages can result in the system no longer being able to update automatically.

Frequency update check: Apresa can check daily for new security updates. In addition, if you want to run the update check immediately, enable the Run now checkbox. Running a security update can take 5 minutes or more, depending on how many packages need to be upgraded.

If anything was upgraded, a confirmation email is sent to the administrator email address.

During upgrade, there can be an interruption of the functionality of the recorder, for example when the database engine needs to be restarted after upgrade.

Server for installing Debian software: This server is not used for security updates, but for installing additional software. Input a nearby server from the mirror list, or alternatively for Debian 9 http://deb.debian.org/debian/ could be used.

Notice: Generally it is not recommended to install additional software, because it could interfere with the normal operation of the recorder.

This server can be used when installing the Debian packages needed for unattended security upgrades.
