Comment 3 for bug 340843

Actually that 0.1 -> 1.0.18 upgrade does tell us something.

Did you do this upgrade using apt-get? Or do-release-upgade, while Ubuntu 8.10 was still not released?

lanscape-client-0.1 was a placeholder package, not really containing any files. The do-release-upgrade program was at some point during the 8.10 development cycle modified to *not* upgrade this placeholder package to the real one, but if you did the upgrade before this change, that would explain how you ended up with the landscape-client daemons installed and running.

So, no, Ubuntu desktop or server don't install landscape-client by default. The closest to this is ubuntu server, which installs landscape-common by default, but that does not run any daemon and just provides the landscape-sysinfo tool responsible for some machine statistics that is shown during login (via motd).
