Updating the application from a previous version
Only Kaspersky Endpoint Security 12.0 for Linux can be updated to Kaspersky Endpoint Security 12.1 for Linux.
Upgrading earlier Kaspersky Endpoint Security versions to version 12.1 is not supported. If you have an earlier version of Kaspersky Endpoint Security installed, you need to first uninstall it and then install Kaspersky Endpoint Security 12.1 for Linux.
You need to prepare to install before installing Kaspersky Endpoint Security.
The application update procedure involves the following steps:
- Updating the Kaspersky Security Center Network Agent
If you are managing Kaspersky Endpoint Security using Kaspersky Security Center, you must update the Network Agent on the protected devices. The update is performed by installing a new version of Network Agent.
If the Network Agent is not updated, the application cannot be managed using Kaspersky Security Center.
On a device running the Astra Linux Special Edition operating system, we recommend to update Network Agent remotely using Kaspersky Security Center, since updating using the command line in the Kaspersky Security Center administration console creates a new copy of the same managed device, and the old one becomes inaccessible.
The application continues working correctly during the Network Agent update.
- Updating the Kaspersky Endpoint Security administration plug-in
If you are managing Kaspersky Endpoint Security using Kaspersky Security Center, you must update the Kaspersky Endpoint Security management web plug-in or MMC plug-in, depending on the console that you are using to manage Kaspersky Security Center.
- Updating the application and graphical user interface on protected devices
You must update the application installed on protected devices. The updated application retains the application usage mode that was selected during installation. If you want to use the application in a different mode, you must uninstall the application and then perform the installation and initial configuration of the application.
If Kaspersky Endpoint Security is being used in Standard mode and you are using the graphical user interface of the application, you must also update the graphical user interface.
You can update the application and the application's graphical user interface in the following ways:
If an error occurs while updating the application, the update is rolled back and the previous version of the application is started. In this case, an error message will be displayed, but the package manager (rpm/dpkg) will indicate the new version.
Even if Kaspersky Endpoint Security is launched before the update process start, if the update is completed successfully, a new application version is launched.
When you update the application to a newer version, the dump files of the previous version are deleted.
If Kaspersky Endpoint Security is being used in Standard mode, we recommend starting the database update task after updating the application.
