Hello, I work in Nokia as a Software QA engineer and I am trying to install Ceph on centOS 7.4 version. But I am getting this error with the following output: - vmgoscephcontrollerluminous][WARNIN] Error: Package: 2:ceph-common-12.2.12-0.el7.x86_64 (Ceph) [mvmgoscephcontrollerluminous][WARNIN] Requires: liblz4.so.1()(64bit) [mvmgoscephcontrollerluminous][WARNIN] Error: Package: 2:ceph-osd-12.2.12-0.el7.x86_64 (Ceph) [mvmgoscephcontrollerluminous][WARNIN] Requires: liblz4.so.1()(64bit) [mvmgoscephcontrollerluminous][WARNIN] Error: Package: 2:ceph-base-12.2.12-0.el7.x86_64 (Ceph) [mvmgoscephcontrollerluminous][WARNIN] Requires: gperftools-libs >= 2.6.1 [mvmgoscephcontrollerluminous][WARNIN] Available: gperftools-libs-2.4-8.el7.i686 (base) [mvmgoscephcontrollerluminous][DEBUG ] You could try using --skip-broken to work around the problem [mvmgoscephcontrollerluminous][WARNIN] gperftools-libs = 2.4-8.el7 [mvmgoscephcontrollerluminous][WARNIN] Error: Package: 2:ceph-mon-12.2.12-0.el7.x86_64 (Ceph) [mvmgoscephcontrollerluminous][WARNIN] Requires: liblz4.so.1()(64bit) [mvmgoscephcontrollerluminous][WARNIN] Error: Package: 2:ceph-base-12.2.12-0.el7.x86_64 (Ceph) [mvmgoscephcontrollerluminous][WARNIN] Requires: liblz4.so.1()(64bit) [mvmgoscephcontrollerluminous][DEBUG ] You could try running: rpm -Va --nofiles --nodigest [mvmgoscephcontrollerluminous][ERROR ] RuntimeError: command returned non-zero exit status: 1 [ceph_deploy][ERROR ] RuntimeError: Failed to execute command: yum -y install ceph ceph-radosgw Does anyone know about this issue like how can I resolve package dependencies?
