Unable to install RPM package

Hello:
I am using openSUSE Leap 42.1 (x86_64).
Trying to install an RPM package from https://build.opensuse.org/package/binary/multimedia:musescore2/musescore?arch=x86_64&filename=musescore-2.1.0-1.1.x86_64.rpm&repository=openSUSE_Leap_42.1

After downloading, when clicked, it doesn’t start installation, rather it opens the ARK program (which is a file compression/decompression application).

Also tried with YAST, after import, it tells: “Error loading package list from /home/jamil/Downloads/musescore-2.1.0-1.1.x86_64.rpm”.

Can you please help, where did I make a mistake ?

Thanks.

Hi
Look at using zypper as root user;


su -
zypper in http://download.opensuse.org/repositories/multimedia:/musescore2/openSUSE_Leap_42.1/x86_64/musescore-2.1.0-1.1.x86_64.rpm

or

zypper in /home/jamil/Downloads/musescore-2.1.0-1.1.x86_64.rpm

PS, openSUSE Leap 42.1 is out of maintenance (EOL) so you should look at upgrading your system.

Thank you.
I could successfully installed using zypper.
