(Partal) Linux Instalation Failure?

Ran librepcb-installer-0.1.4-linux-x86_64.run as administrator.
Got error messages about Desktop database. Would like to attach InstallationLog.txt but can’t see how? Last few lines are:

Hi,

Maybe the command update-desktop-database is simply not available on your system? What distribution are you using? On Debian based distributions the package desktop-file-utils might need to be installed.

Hi,
Thank you for the suggestion. I am running openSUSE LEAP15.1 and update-desktop-database is available. See (from log file snippet given in opening over):
[53497] - arguments: update-desktop-database, /usr/local/share/applications
[53497] Done
What I suspect, is wrong are the arguments? I do not have a:
/usr/local/share/applications
folder?
