Hi All, I.m going to install OpenStack Xena on CentOS 8.5. I'm following the TripleO in RDO Xena Release. I followed the RDO guide & enable the required packages. Package installation is successful, but the pulling of the triple container imagers using the command was unsuccessful. Here is the command I use. openstack tripleo container image build --base ubi8 --debug --distro centos \ --namespace tripleoxena --prefix openstack --tag cloudsig-xena \ --push --registry 172.22.1.10::8787 \ --volume /etc/yum.repos.d:/etc/distro.repos.d:z --volume /etc/pki/rpm-gpg:/etc/pki/rpm-gpg:z --volume /etc/dnf/vars:/etc/dnf/vars:z \ --work-dir ~/workdir After executing the above command error was received & I attach it to this mail. Please provide me with a solution for this. -- Thanks & Regards, *Suranga Prabhath,* System Administrator hSenid Software International *Sri Lanka* *M* : +94 00 000 0000 *P* : +94 11 268 3751 *F* : +94 11 268 3951 *Singapore* *M* : +65 00 000 000 *P* : +65 65 332 140 *F* : +65 62 910 023 <http://www.hsenid.com/> <http://www.hsenidmobile.com/> <https://www.facebook.com/hSenid.Software.International/> <https://twitter.com/hsenid_biz> <https://www.linkedin.com/company/hsenid-business-solutions> <https://www.youtube.com/user/hsenidbiz> *www.hSenid.com* <http://www.hsenid.com/> <https://www.google.com/url?q=http://www.hsenidmobile.com/&source=gmail-html&ust=1630670716868000&usg=AFQjCNGq31WUp1TMmFUQjIuDHaKf_BdIvQ> *Disclaimer*: This email and any files transmitted with it are confidential and intended solely for the use of the individual or entity to which they are addressed.
