Posted by Vincent De Maertelaere, Last modified by Dries Decock on 16 April 2019 05:14 PM


When a new ByteBlower server software version has been released, the ByteBlower server requires a software update.

This "How to" describes how to update a ByteBlower server.

Update from the ByteBlower GUI

Starting from version 2.5, the server can be upgraded from the GUI. This has the additional benefit that the server doesn't need an internet connection: the GUI will act as a proxy server!

Start the upgrade from the GUI

In this example, we upgrade a server running version 2.8.2 to version 2.9.26. Let's start:

Please be patient...

The upgrade can take a while. The upgrade of the server requires two reboots, some downloads, ... To see the progress, go to the progress view. When the server downloads packages, you will see the amount of data proxied by the GUI in the progress view:

Check if the upgrade has finished

You can verify if the upgrade has finished by refreshing the server in the server view. If the upgrade has finished, the server will become available again and the new version will be visible next to the server:

Connect to the ByteBlower

To update the ByteBlower server, you'll need a console on the ByteBlower. This can be achieved in 2 ways.

  1. Physical console: Connect a screen and a keyboard.
  2. SSH: Log in from the terminal (Linux or Mac) or with an application such as PuTTY (Windows).

Login using root and the password ("excentis" by default)

Go into update mode

The ByteBlower server needs to reboot into a specialized update-mode.

To get into this specialized update-mode, execute

# byteblower-update
To proceed, we need to reboot the system. Is this ok? (yes/no) yes

Now the ByteBlower server will reboot into update mode. On older systems (ByteBlower server 1100 and 1200), this can take a little while.

When the server rebooted into its specialized update-mode, the ByteBlower server will keep it's vital information: IP address, SSH-keys, root password.

After login, the ByteBlower update system will launch.

(Optional) Fixed IP settings
