Hi Team, I was trying to install Undercloud on Centos 8 using the link below, but facing error in executing "openstack undercloud install" command. The error is in prefetch image Steps followed: 1. Created a non root stack user - sudo useradd stack - sudo passwd stack # specify a password - echo "stack ALL=(root) NOPASSWD:ALL" | sudo tee -a /etc/sudoers.d/stack - sudo chmod 0440 /etc/sudoers.d/stack - su - stack 2. Install the python-tripleo-repos - sudo dnf install -y https://trunk.rdoproject.org/centos8/component/tripleo/current/python3-tripl... - In order to install victoria release, executed the command - *sudo -E tripleo-repos -b victoria current ceph* 3. As per the document, "*The remaining repositories configuration steps below should not be done for stable releases!"* - *So, I didn't executed the command* - "sudo -E tripleo-repos current-tripleo-dev ceph" - *Is my understanding correct? This step has to be skipped in case we are going with a stable victoria release?* 4. Modified undercloud.conf file and executed the command - openstack undercloud install *ISSUE:* 2021-09-20 11:16:18,724 p=59556 u=root n=ansible | 2021-09-20 11:16:18.723422 | 525400a8-fc39-4771-208c-000000000e71 | FATAL | Pre-fetch all the containers | undercloud | item= quay.io/tripleovictoria/openstack-swift-account:current-tripleo | error={"ansible_loop_var": "prefetch_image", "changed": false, "msg":" *Failed to pull image quay.io/tripleovictoria/openstack-swift-account:current-tripleo <http://quay.io/tripleovictoria/openstack-swift-account:current-tripleo>", "prefetch_image": "quay.io/tripleovictoria/openstack-swift-account:current-tripleo <http://quay.io/tripleovictoria/openstack-swift-account:current-tripleo>"}* 5. In order to eliminate the problem, I manually installed the image - - sudo podman pull *quay.io/tripleovictoria/openstack-swift-account:current-tripleo <http://quay.io/tripleovictoria/openstack-swift-account:current-tripleo>* After re-executing, then it again failed for the keystone image, which was already installed on the system. I verified in *sudo podman images* command *I tried running this 5-6 times and issue generates randomly for any openstack image ( sometimes for rabbitmq sometimes for swift, keystone) which is already installed in machine* Can someone please help or suggest what step I am missing Note: This I have tried using Centos 8 Stream and Centos 8.4(using --no-stream), but same issue is observed in both Regards Anirudh Gupta
