OVA Management
The Helix Swarm OVA is installed with Ubuntu 16.04 LTS. Ubuntu's "Long-Term Support" releases receive security updates periodically over their 5-year support window. We recommend that use of the OVA involve package updates from time to time, which can be accomplished as follows:
-
Log in to the OVA as root. The password for the root account was established during setup.
-
Update the catalog of available packages:
# apt-get update -
Download and install any updated packages:
# apt-get upgrade
Tip
See "Package management with APT" for more information:
Dependency Conflicts
Ubuntu software packages are often dependent on other packages that provide, for example, common libraries, utilities, and configuration. Occasionally, an upgraded package may have differing dependencies than its previous version, which can lead to dependency conflicts that can prevent package updates from completing successfully.
Should this situation occur with the Swarm OVA, use the following command to use "smart" conflict resolution, which attempts to upgrade the most important packages at the expense of less important packages if necessary:
# apt-get dist-upgrade
Warning
Upgrading packages could potentially make the OVA-hosted Swarm no longer functional. If you use the Swarm OVA in a production environment, perform the package updates on a copy of the OVA and test that Swarm continues to function properly.
