Problem updating to core 8.6.7.0 on SLES 12 SP3

I try to update kopano from 8.5.8.2 to 8.6.7.0 on SLES 12 SP3 using YaST2.
But it failed with unresolved dependencies:
python3-dateutil is needed by python3-kopano-8.6.7.0-16.1.x86_64
python-magic is needed by kopano-search-8.6.7.0-16.1.x86_64

What am I missing? Where did I get python3-dateutil for SLES12-SP3?

Check if you already have
/usr/lib/python3.6/site-packages/dateutil/

Currently only python2 is installed.
I could install python3 via YaST2 Software Management. But python3-dateutil is missing. Couldn’t find any package that provides dateutil.

Thanks

Is kopano for SLES realy needing Python3? Or is it a packaging bug and only python2-dateutil needed?

Maybe one of the developers could bring a little bit light on this? Did they have testet that release on SLES 12 SP3?

I run kopano 8.6.7.0-16.1 on SLES 12 SP3.
This modules are installed: python2-kopano-8.6.7.0-16.1.x86_64, python-dateutil-2.4.2-14.2.noarch and python-magic-5.19-9.1.x86_64 . No Python3 Kopano modules installed. We use the PHP5 packages.

Update to kopano 8.6.8.0 was working.
Was a while away from office. So it needed a while to run the update.
Thanks
