I tried to install trinity desktop by following instruction on 
https://wiki.trinitydesktop.org/OpenSUSEInstall.

All run well, but after the command 
   zypper install trinity-desktop

the system gave following error message:
Problem: nothing provides libaudio.so.2()(64bit) needed by trinity-kttsd-
contrib-lugins-14.0.4-1.oss422.x86-64

As I tried only to install some trinity software using yast I got a similar 
error:
nothing provides lib|lm|mf-2_2.so.22()(64bit) needed by trinity-kttsd-contrib-
lugins-14.0.4-1.oss422.x86-64

What can I do to solve that?

PS: packman repository is implemented 
(http://ftp.gwdg.de/pub/linux/misc/packman/suse/openSUSE_Leap_42.2/)
