Hi,
I try to calcule Atlas native tasks with a Debian 9.9 system ( singularity-container package from the backports repos ) .
I have no problems with Theory Native ones but with Atlas native it's another thing .
Only one task has been completed .
All the following ones have valide error state : https://lhcathome.cern.ch/lhcathome/results.php?hostid=10516558&offset=0&show_names=0&state=0&appid=14
What's wrong ?
Thank you for your response .

Hi Elgrande,
My machines will happily run 4 x single-core Theory but can only successfully run 1 single - core Atlas due to the memory requirement. Limit it to 1 x 1-cpu task and see if that is successful. Have a look at Yeti's Checklist

This error

FATAL Conditions database connection COOLOFL_TRT/OFLP200 cannot be opened - STOP"

means the WU cannot contact ATLAS database services. Maybe you have a firewall blocking the traffic?

Thank you for showing me the right path .
My firewall was the culprit .
I found good information on this page : http://lhcathome.web.cern.ch/faq/troubleshooting?page=1
I was obliged to open tcp ports 3125,3128,8000,8080 and 23128 to fix the problem .
Now I can calculate Atlas simulation tasks without Virtualbox .
Fantastic .
