Hi experts, last night I've installed Kubuntu, looks great! But how do I install more applications? Let say I've dowloaded skype for Ubuntu. Could not figure out how to install it. How does installation process work for downloaded apps? I've found Kubuntu application with a huge list of apps that can be installed from there but skype for wasn't there... Also any good tutorials, websites etc. how to learn Linux Kubuntu? Thank you.
