Hi Saul: Some more details info: 1) StarlingX currently is using Ceph Mimic Release (13.2.2), which was not active release from Ceph community [1]. 2) CentOS community only officially provides Ceph Nautilus (14.xx) and Octopus (15.xx) RPMs for centos8 [2]. Based on these information , either find 3rd party provides ceph M release rpms for centos8 , or build from src/srpm is needed for centos 8 [1] https://docs.ceph.com/en/latest/releases/ [2] http://mirror.centos.org/centos/8/extras/x86_64/os/Packages/ Thanks.

Can you provide more details about what the issues where with CentOS-8 and/or python3? Thanks Sau!
