Adding a package repository and installing OpenSCADA from that
Package repositories are provided by the OpenSCADA project itself, whose service information is usually located along with the packages themselves and is updated automatically at the building, that is, these repositories are most up-to-date and preferable. Although OpenSCADA packages can still be found in the repositories of such Linux distributions: ALTLinux and distributions based on the package base Fedora, but they rather will be old ones since the packages building to the distribution repositories from the developers is not practiced right now!
