The Canonical/Ubuntu Landscape service has been around for as long as I can remember using Ubuntu. A free trial period is enabled (re-enabled?) when a new installation occurs, that allows for a server administrator to see performance metrics and uptime information for any hardware that is running the client. After the trial ends, it is still a quick means of visually observing some key statistics in the terminal MOTD at login. I’d also noticed that it was still doing DNS lookups to “
landscape.canonical.com” on a regular basis, and while I did not look for it, I assume that some information was still being collected and reported upon.
As there are MANY other ways to get server performance information, I decided that it was time to be rid of landscape itself.
Removal is easy, as only one line is required… I chose to “purge” all references, though you can “remove” if you feel inclined to leave any configuration for possible later re-installation.
sudo apt-get purge landscape-client landscape-client-ui landscape-client-ui-install landscape-common
