Introduction

The BlueMind subscription includes a simplified, tried and tested update system.

Updating BlueMind to a corrective or adaptive version is made easier, safer and faster thanks to the graphical admin tool.

Prerequisites

Subscriptions

To access BlueMind update tools, you must have a valid and current subscription installed.

Ancre
setup-passwd setup-passwd

Access to the setup wizard

Updates require access to the setup wizard (https://<your.server.com>/setup) for which you were provided a password at the end of the post-installation process.

In case you lost this password, there are two ways of recovering it:

1. Before any installation operation: Access the administration console as global administrator admin0 and go to System management > System configuration > "Reverse proxy" tab: enter the new password and save.
2. Using command line in console mode:
   

   • connect to Log into the BlueMind server as root and type the following command:

     Bloc de code
     rm -f /etc/nginx/sw.htpasswd; htpasswd -b -c /etc/nginx/sw.htpasswd admin admin

   • connect to Log into the /setup URL using admin/admin as username/password
     This step is necessary required even if you have not reached the update step yet.

Repository signature

Repositories are now signed for all supported Ubuntu/Debian distributions.

Repository signature is required for Ubuntu 18.04 and Debian 9 which are supported by BlueMind 3.5.9.

You may, if you need or want to, manually import the key on all our supported distributions using the following command:

curl https://pkg.bluemind.net/bluemind-deb.asc | apt-key add -

Otherwise, a warning may come up during earlier version updates. This will not disrupt or interfere with updates.

Points of Caution 

We recommend that you carefully read the page Deploiement BlueMind 4 - points de vigilance before any important version update.

Updating from 4.0 to 4.1

Inbox subfolders

In BlueMind versions 4.0.x, folders created in the inbox by Outlook are not mailbox folders but virtual folders. BlueMind 4.1 brings inbox subfolder support.

When you update from BlueMind 4.0.x to 4.1, virtual folders users may have created will not be migrated and will be deleted. To prevent this and keep these folders, we recommend that you move virtual folders outside the inbox before you perform the update. You can them put them back into the inbox where they will be created again as mail folders.

Update instructions

Repositories are registered as soon as the subscription is installed, as a result, BlueMind will be updated automatically when the system is updated.

Preparing for the update

For updates from BlueMind version 4.1 or above, the process must always be prompted. This gives you greater control over versions and reduces the risk of errors: the target version can now be left open to allow updates to the latest published version or, on the contrary, it can be frozen to prevent unintentional updates. This also helps ensure that the server's major version as well as additional packages are conformed to.

This can be done in the admin console:

1. Go to System management > Update BlueMind
2. Click "Setup": the latest available version will be installed.

Update Procedure

Le processus de mise à jour de BlueMind commence par la mise à jour des paquets sur tous les serveurs de l'installation, au moyen des commandes déjà utilisées lors de l'installation. Les étapes 1 et 2 sont donc à appliquer sur toutes les machines concernées. Ensuite, la phase de mise à jour proprement dite sera jouée une seule fois, en se connectant à l'adresse /setupThe BlueMind update procedure begins with an update of the packages on all the installation's servers using the commands already used for installation. Steps 1 and 2 therefore must be applied to all the machines concerned. Then, the update itself will have to be played just once, by login into the /setup url:

1. Connect as root sur chacun des serveurs de la plate-formeLog in as root on each platform server.

2. Update the packages sur chacun d'euxon each:

   Remarque
   If you want to minimize service downtime, you can pass the update command with the "download-only" option, which enables you to download all the packages ahead of the update. This does not interrupt or slow down services, which means it can be done at any time of day or night. You can then run the "upgrade" command at a more convenient time and therefore reduce service downtime.

   Repeat these commands on each platform server.

   Info
   You may get a warning message about repository signature during earlier version updates. This does not disrupt the update, it is a mere warning. To remedy this issue, please refer to 2.3.c: Repository signature above.

3. Go to the setup wizard https://<your.server.com>/setup
   
   

   Astuce
   Note: this step requires the setup wizard's password - see paragraph 2.2 above.

4. Click "Update" to start the automatic update process.
5. Once this is done, a message informs you that configuration was successful:

  BlueMind is then available at its usual url.
