How to get Rosegarden
Preparing for Rosegarden
Rosegarden can benefit from running on a system that is well tuned for audio and low-latency use (although this is much less important than it used to be). Some distributions have at least one specialised low-latency kernel package available via some sort of additional multimedia distribution or repository; consider using one of these. For example, Ubuntu -> Ubuntu Studio; Fedora -> PlanetCCRMA. See this page for more options. In most cases the choice of a multimedia distribution will make no difference to which version of Rosegarden you can use: it will affect the type of Linux kernel and other audio services available, and consequently how well Rosegarden will run.
Distribution packages
Installable binary packages for many major Linux distributions are available via the distributions' standard package repositories. Please consult your distribution's documentation for more details on how to obtain and install packages from these repositories. These packages tend to be easy to install and use less space. The downside is that they tend to be quite outdated.
flatpak
A flatpak with all the dependencies is available on flathub. flatpak's tend to be more up to date and they don't require any dependencies to be installed. On the downside they may be bigger since they have a complete copy of the dependencies, though these are shared across flatpaks.
Download Rosegarden from flathub.
