     Hello. 
        This command : 'sudo apt install yum' I get a message
        saying -  
       
    Reading package
          lists... Done 
          Building dependency tree... Done 
          Reading state information... Done 
          Package yum is not available, but is referred to by another
          package. 
          This may mean that the package is missing, has been obsoleted,
          or 
          is only available from another source 
           
          E: Package 'yum' has no installation candidate 
    Am I doing something
      wrong? 
      How can I install yum in my Debian 12?
