If something is described as installable on Ubuntu, what does this limitation really mean?:

I’m thinking of installing manjaro, but a lot of the software I use is described as to be installed on Ubuntu (ros-kinetic could be one such example). So how does installing software on other distros compare? If something is on apt, how likely am I to find it on pacman?
