I never ran an ubuntu server, until recently, I needed a bigbluetutton VM, and, since installing on ubuntu it's easier (just add the repository), I installed it on that distro.
But, when I log on console, i get this:
24 packages can be updated. 0 updates are security updates.
* System restart required *
So I do apt-get update and apt-get upgrade, but it says no packages to upgrade. How to update those 24 packages?
