Install TeXLive on OpenSUSE

Question

I have an OpenSUSE Leap 15.2. operating system.

I have downloaded this texlive.ymp file from this link.

I go to YaST > Software Manager (as suggested here), but then I don't know what to do. Where can I find this texlive.ymp file?

I have also tried to do sudo zypper install texlive-latex as suggested here, but after I insert my password I get (loosely translated):

System management is blocked by the application with pid 14461 (/usr/bin/ruby.ruby2.5).
Please close this app before trying again.

EDIT:

So the solution for me has been:

1. Go to here and download install-tl-unx.tar.gz
2. Go to the folder where it has been downloaded and extract the file
3. cd to the extracted folder
4. perl install-tl
5. Enter command: i

If you don't have permission to edit /usr/local/, go there and run sudo mkdir texlive, then chmod +rwx texlive.
