Upgrading Kaspersky Security Center Web Console on Astra Linux in the closed software environment mode

This article describes how to upgrade Kaspersky Security Center Web Console Server (also referred to as Kaspersky Security Center Web Console) on the Astra Linux Special Edition operating system.

To upgrade Kaspersky Security Center Web Console:

1. Make sure that the device on which you want to upgrade Kaspersky Security Center Web Console is running one of the supported Linux distributions.
2. Read and accept the End User License Agreement (EULA). If the Kaspersky Security Center Linux distribution kit does not include a TXT file with the text of the EULA, you can download the file from the Kaspersky website. If you do not accept the terms of the License Agreement, do not upgrade Kaspersky Security Center Web Console by using the installation file.
3. Use the same response file that you prepared before installing Kaspersky Security Center Web Console. The response file name is ksc-web-console-setup.json, and the file location is /etc/ksc-web-console-setup.json.

   If the response file does not exist, create a new response file that contains the parameters for connecting Kaspersky Security Center Web Console to Administration Server. Name the file ksc-web-console-setup.json, and then place it in the /etc directory.

   Example of a response file containing a minimal set of parameters, and the default address and port:

   {

   "address": "127.0.0.1",

   "port": 8080,

   "trusted": "127.0.0.1|13299|/var/opt/kaspersky/klnagent_srv/1093/cert/klserver.cer|KSC Server",

   "acceptEula": true

   }

4. Ensure that in the /etc/digsig/digsig_initramfs.conf file, the DIGSIG_ELF_MODE parameter is specified as follows:

   DIGSIG_ELF_MODE=1

5. Ensure that the astra-digsig-oldkeys compatibility package is installed.

   If this package is not installed, run the following command:

   apt install astra-digsig-oldkeys

6. Create a directory for the application key, if it does not exist:

   mkdir -p /etc/digsig/keys/legacy/kaspersky/

7. Place the application key /opt/kaspersky/ksc64/share/kaspersky_astra_pub_key.gpg in the directory created in the previous step:

   cp kaspersky_astra_pub_key.gpg /etc/digsig/keys/legacy/kaspersky/

   If the Kaspersky Security Center Linux distribution kit does not include the kaspersky_astra_pub_key.gpg application key, you can download it by clicking the link: https://media.kaspersky.com/utilities/CorporateUtilities/kaspersky_astra_pub_key.gpg.

8. Update the RAM disks:

   update-initramfs -u -k all

   Reboot the system.

9. Under an account with root privileges, use the command line to run the setup file. You receive the setup file by downloading it from the Kaspersky website.

   To upgrade from a previous version of Kaspersky Security Center Web Console, run the following command:

   $ sudo dpkg -i ksc-web-console-[build_number].x86_64.deb

   This starts unpacking the setup file. Please wait until the installation is complete.

10. Restart all of the Kaspersky Security Center Web Console services by running the following command:

    $ sudo systemctl restart KSC*

When the upgrade is complete, you can use your browser to open and log in to Kaspersky Security Center Web Console.
