The Installer uses the file '/etc/os-release' to determine which OS is currently running on the Host.
Therefore the Value of 'PRETTY_NAME' is read from the File.
I would suggest using the value 'ID_LIKE' instead, as it just provides the distribution instead of the specific OS version.
For example, openSUSE Leap 15.1 is supportet but openSUSE Leap 15.2 isn´t.
