Packages repositories based on the package manager APT (Debian, Ubuntu, ALTLinux) — are added by the location of the downloaded file "openscada.list" to the /etc/apt/sources.list.d folder or by editing the /etc/apt/sources.list file by inserting one line:
Debian (LTS and Work, Automation Linux repository): "deb http://ftp.oscada.org/Debian/9/openscada ./"
Ubuntu (LTS): "deb http://ftp.oscada.org/OpenSCADA/LTS/Ubuntu/18.04 ./"
Ubuntu (Work): "deb http://ftp.oscada.org/OpenSCADA/Work/Ubuntu/18.04 ./"
$ apt-get update $ apt-get install openscada-model-aglks
$ apt-get update $ apt-get install openscada-Model.AGLKS
Adding the signature verification key (the authenticity) of the repository and packages in it (not necessarily and not in all repositories):
$ wget -O - http://ftp.oscada.org/Misc/pkgSignKey | sudo apt-key add -
