Hi, I was not able to find any complete guide on how to build ceph (14.2.x) from source, create packages and build containers based on those packages. Ubuntu or centos, does not matter. I tried so far: ############### docker pull centos:7 docker run -ti centos:7 /bin/bash yum install -y git rpm-build rpmdevtools wget epel-release yum install -y python-virtualenv python-pip jq cmake3 make gcc-c++ rpm-build which sudo createrepo git clone https://github.com/ceph/ceph cd ceph git checkout v14.2.13 ./make-srpm.sh ./install-deps.sh ################# but install-deps.sh fails with: Error: No Package found for python-scipy The following error message appeared before: ---------------- http://vault.centos.org/centos/7/sclo/Source/rh/repodata/repomd.xml: [Errno 14] HTTP Error 404 - Not Found Trying other mirror. To address this issue please refer to the below wiki article https://wiki.centos.org/yum-errors If above article doesn't help to resolve this issue please use https://bugs.centos.org/. http://vault.centos.org/centos/7/sclo/Source/sclo/repodata/repomd.xml: [Errno 14] HTTP Error 404 - Not Found -------------------- centos:8 fails as well. dependency error: Error: Problem: package python36-rpm-macros-3.6.8-2.module_el8.1.0+245+c39af44f.noarch conflicts with python-modular-rpm-macros > 3.6 provided by python38-rpm-macros-3.8.0-6.module_el8.2.0+317+61fa6e7d.noarch - conflicting requests Any helpful links?
