Ubuntu and Lubuntu have different "Supported until" dates for Precise Pangolin (since Ubuntu have LTS releases, but Lubuntu does not).
What exactly does this mean, for me as a user, if I have Lubuntu installed, given that both distros use the same apt repository? – Will I not get security updates for Lubuntu-related packages after April 2013? If so, which packages are those? Or are there any other consequences?
EDIT: Added the bold text.
EDIT 2: I'm wondering what updates etc. I'll get be on a Lubuntu system after October 2013. (Given that both distros use the same apt repo, and that apt repo will continue to be updated until mainline Ubuntu is no longer supported, in April 2017.)
