Hi @IVG, and welcome!
Yes, Linux can be intimidating, but it is much, much, much better than the alternative. However, do not fear. Rather, look here:
Manjaro is not Debian, or Ubuntu, and as such doesn’t have *apt or apt-get or something in that line. Rather, Manjaro uses pamac.
Go ahead and reead up on that. It’s good knowledge. Also important knowledge.
