Upgrade to SLES15 breaks Gapcmon for APCUPSD

Everything went with updating Xen server to sles15
Only thing is no longer working is the Gapcmon for the APCUPSD
This used to be a tray icon, but I can no longer find it,
looking for the package, but even the gapcmon package has disappeard.
Downloaded the seperate package, since not available through novell.
But I cannot seem to get it to work.
Anyone else with this problem ?

Update ; installing gapcmon reports a key error
states it needs : zypper --no-gpg-checks install PACKAGE

Now one step further :
Failed to load module “canberra-gtk-module”
strace : access("/root/.gtk-2.0/2.10.0/i586-suse-linux-gnu/modules/libcanberra-gtk-module.so", F_OK) = -1 ENOENT (No such file or directory)

libcanberra-gtk2-module shows installed in /usr/lib64/gtk-2.0/modules/
Any ideas ?

Yes, see comment #17:

So now what ?
