A month ago I moved from Windows to Ubuntu. While using Ubuntu I notice some things about installing software. I've read some installation guides about installing software, and been curious about two things: the first thing is the dependencies and the second one is the repositories.
I've search over the internet, and by definition I found this:
- A dependency is a file that something you are trying to install requires.
- A software repository is a storage location from which software packages are retrieved for installation.
But still I do have some questions.
- Do I really need this two things as always? Why?
- How can I identify which and what repositories and dependencies to use?
- What things must I remember before installing dependencies and repositories?
- Is there a good book to read about these two things?
- Another option to deal with aside from using terminal? Should I use software center?
