Yes. You can also use Synaptic, the GUI front-end to to apt.
You can also download raw source code from various websites, compile and install, but a package manager (apt or yum for RedHat-based flavors of Linux) will save you from dependencies and version mismatches (i.e., you have to have have xyz before you can install abc but abc v. 4 works best with mno v. 2) not to mention going to find all the different sites that provide the software you are interested in installing.
git is actually going to pull raw source code for op25 but the install.sh then uses apt to get a lot of the other packages you need so you are only compiling op25 itself.
