SUMMARY
Package ksysguard5 (and some others) cannot be installed on the current openSUSE Leap.

STEPS TO REPRODUCE
1. On Leap 15.1, add the KDE repos; see: https://en.opensuse.org/SDB:KDE_repositories
2. zypper in ksysguard5-5.18.90
3. 

OBSERVED RESULT
Problem: ksysguard5-5.18.90-lp151.264.1.x86_64 requires libprocesscore.so.9()(64bit), but this requirement cannot be provided
  not installable providers: libksysguard5-5.18.90-lp151.257.1.x86_64[KDE_Frameworks5]
...

EXPECTED RESULT
The installation succeeds.

SOFTWARE/OS VERSIONS
Windows: 
macOS: 
Linux/KDE Plasma:
(available in About System)
KDE Plasma Version:  upgrading 5.18.5 -> 5.18.90
KDE Frameworks Version: 
Qt Version: 5.14.1

ADDITIONAL INFORMATION
The previous package libksysguard5-5.18.5 includes /usr/lib64/libprocesscore.so.7.  It appears that the 5.18.90 package does not include the required libprocesscore.so.9, and it's not available in any other package that I can find.  This in turn means a number of other packages won't install either; in my case I'm left with a version mix and some broken functionality.  I'm hoping this is just a minor error in the packaging process.

What is the correct severity for uninstallable packages?  Please adjust accordingly!
