could someone explain to me how software/program installations/removals work on Ubuntu? I know there is a software centre but some of the software I want isn't in it. There is also the apt-get command but I am not entirely sure how that works. For every program I want to install using apt-get there can be many different ways I find how to do it when I google it. Everyone seems to have a different ways! I assume apt-get is linked to a repository but how do I see this repository or find the repository a program I might want to install sits in, and its dependencies. My biggest gripe when switching from Windows to Linux is the install process. On windows, you download the installer, click run and bang it works. When I want to remove a program I simply choose uninstall program in the control panel. Why is it such a hassle in Linux? If there is an easy way of doings things with apt-get that you would recommend to a newbie could you please tell!
